Missing a pill is common. And when intercourse took place around the time of the missed pill, one question comes up immediately: "Am I at risk of being pregnant?"
The answer depends on several factors:
- the exact name and type of pill;
- the delay since the usual time of taking it;
- the number of missed tablets;
- the position of the missed tablet within the pack;
- whether unprotected intercourse has taken place;
- and, for certain pills, specific rules given in the leaflet.
There is therefore no single rule valid for all pills.
The first step is to check your pill's leaflet, then quickly ask a pharmacist, doctor, or midwife for advice when intercourse that may be at risk has taken place.
From how many hours is a missed pill considered at risk?
The tolerated delay depends on the contraceptive.
French recommendations notably distinguish between pills according to their composition. Some progestogen-only pills have a tolerated delay that differs from other pills, and certain specific products have their own instructions.
This is why the rule "I'm less than 12 hours late, so everything is fine" must not be applied blindly to all pills.
The leaflet of the specific product being taken remains an essential reference.
What should you do immediately when you notice a missed pill?
When the delay remains below the tolerated limit for the pill concerned, the general recommendations are to:
- take the missed tablet as soon as the omission is noticed;
- take the next tablet at the usual time.
This may result in taking two tablets on the same day.
When the tolerated delay is exceeded, the appropriate course of action depends more on the contraceptive and the situation.
Why is the exact name of the pill important?
Because not all pills work in exactly the same way.
There are notably:
- combined oestrogen-progestogen pills;
- progestogen-only pills;
- packs containing only active tablets;
- packs containing both active and inactive tablets;
- certain pills with specific regimens.
The consequence of a missed pill is therefore not necessarily identical from one product to another.
When calling a pharmacist or attending a consultation, it is useful to have the box or the exact name of the contraceptive to hand.
I missed an active tablet: what should I do?
The general French recommendations state that, when the tolerated delay is exceeded, the last missed tablet should be taken promptly, and the pack should then be continued according to the instructions applicable to that pill.
Temporary barrier contraception, notably a condom, may be necessary.
The exact duration and how to continue the pack depend on the pill and the position of the missed tablet.
For certain combined pills, a missed tablet located towards the end of the active tablets may mean the following pack must be started directly, with no hormone-free interval.
It is nevertheless necessary to check the leaflet of the pill concerned.
And if I missed a placebo or inactive tablet?
An inactive tablet does not contain the contraceptive hormones responsible for the pill's effect.
Missing an inactive tablet therefore does not carry the same significance as missing an active tablet.
But not all packs are organised in the same way. You need to identify with certainty which tablet was missed, using the leaflet.
I missed several tablets: is the risk higher?
Several consecutive missed tablets can further compromise contraceptive effectiveness.
The appropriate course of action may then differ from that for a single missed tablet.
The Assurance Maladie recommends that, in the case of several missed tablets, you should refer to the applicable instructions and take a pregnancy test if in doubt.
In this situation, seeking prompt advice from a professional is preferable to an approximate interpretation of the pack.
I had intercourse before the missed pill: is there a risk?
Yes, in certain situations.
The risk does not only concern intercourse that takes place after the missed pill.
Sperm can remain capable of fertilisation for several days in the female genital tract. Intercourse preceding the missed pill can therefore be relevant if the missed pill sufficiently compromises the inhibition of ovulation.
French recommendations notably give particular attention to unprotected intercourse occurring in the five days preceding an at-risk missed pill.
Emergency contraception may then be indicated depending on the pill and the situation.
I had intercourse after the missed pill: what should I do?
When contraceptive effectiveness may have been compromised and intercourse without a condom has taken place, the need for emergency contraception must be assessed promptly.
Do not wait for your next period to seek advice: the effectiveness of emergency contraception depends on the delay.
What emergency contraception is available after a missed pill?
In France, there are two main options:
Hormonal emergency contraception
Two molecules are available:
- levonorgestrel: to be used no later than 72 hours (3 days) after the at-risk intercourse;
- ulipristal acetate: to be used no later than 120 hours (5 days).
The sooner emergency contraception is taken, the better.
Copper IUD
The copper intrauterine device is a highly effective method of emergency contraception.
It requires a consultation and insertion by a qualified professional.
The choice between the different options depends notably on the delay, your usual contraceptive, and your individual situation.
Does the "morning-after pill" necessarily have to be taken the morning after?
No.
The term "morning-after pill" can be misleading.
Hormonal emergency contraception should be taken as quickly as possible, without waiting until the next morning if it can be obtained immediately.
Depending on the molecule, it can be used up to 3 or 5 days after the at-risk intercourse.
Does emergency contraception interrupt a pregnancy?
No.
The World Health Organization states that emergency contraceptive pills mainly prevent pregnancy by preventing or delaying ovulation.
They do not interrupt an already established pregnancy.
Emergency contraception is not, therefore, a method of terminating a pregnancy.
Where can you obtain emergency contraception in France?
Hormonal emergency contraception is available at pharmacies.
The Assurance Maladie states that it is dispensed free of charge, with no upfront payment and no medical prescription, to all women, with no age condition, at community pharmacies.
Other services can also support patients according to their age and situation.
After emergency contraception, am I protected for the next acts of intercourse?
Not automatically.
Emergency contraception taken for a given act of intercourse should not be considered general protection against subsequent intercourse in the same cycle.
Resuming your usual contraception and the necessary duration of condom use depend notably on the type of emergency contraception used and your usual pill.
It is particularly important to ask for advice after taking ulipristal, as its interaction with regular hormonal contraception affects the strategy for resuming it.
Should I use condoms after a missed pill?
When the tolerated delay is exceeded, additional protection with condoms may be necessary for several days.
General recommendations often mention 7 days for certain situations, but the exact rule depends on the contraceptive.
Here again, the pill's leaflet and a professional's advice should be followed.
The condom also remains the method that reduces the risk of many sexually transmitted infections.
Vomiting or diarrhoea: is it like a missed pill?
It can be.
If vomiting occurs shortly after taking an active tablet, or in the case of significant diarrhoea, absorption of the pill may be compromised.
The HAS notably states that, in cases of significant diarrhoea or vomiting within four hours of taking an active tablet, it may be necessary to take another tablet.
The precise procedures should be checked in the leaflet of the contraceptive.
I haven't had my period after a missed pill: am I pregnant?
Not necessarily.
Bleeding while on hormonal contraception does not always, on its own, allow you to determine whether or not a pregnancy exists.
But after an at-risk missed pill, the absence of expected bleeding, or any doubt, warrants a pregnancy test.
The Assurance Maladie recommends, in case of doubt, taking a pregnancy test 21 days after the missed pill.
Is a pregnancy test taken right after the missed pill useful?
Not to rule out a pregnancy caused by the recent intercourse.
A test performed too early may be negative simply because any pregnancy is not yet detectable.
The appropriate delay must be respected.
Can you become pregnant during the pill-free week?
When a pill is taken correctly according to its schedule, the planned interval between active tablets is part of how the contraception works.
The problem arises notably when a missed pill unintentionally extends the hormone-free interval, for example towards the end of a pack or at the beginning of the next one.
This is why the position of the missed pill within the pack can change the appropriate course of action.
What should I do if I started my new pack late?
Starting a new pack late can extend the hormone-free interval and compromise contraceptive protection.
The Assurance Maladie notably considers that starting a new pack one day late corresponds to a missed pill requiring the applicable instructions to be followed.
If unprotected intercourse took place around this time, seek prompt advice regarding possible emergency contraception.
Do antibiotics always make the pill ineffective?
No.
Not all antibiotics reduce the effectiveness of oral contraception.
However, certain enzyme-inducing medications can reduce the effectiveness of hormonal contraceptives.
When a new treatment is prescribed or dispensed, you should mention the contraception you are using to your doctor or pharmacist so that interactions can be checked.
How can repeated missed pills be avoided?
A few simple strategies can help:
- taking the pill at a time linked to a daily habit;
- setting an alarm;
- keeping a spare pack when appropriate;
- planning ahead for travel and time-zone changes;
- renewing the prescription before the packs run out.
If missed pills become frequent, this does not mean the person is "bad" at contraception.
It may simply mean that a method requiring a daily action is not the best suited.
An implant or an intrauterine device can then be discussed if the patient wishes and if there is no contraindication.
Key points to remember
After a missed pill, the exact name of the pill is essential: not all pills have the same tolerated delay or exactly the same instructions.
Read the leaflet rather than automatically applying a rule found on the internet.
If the missed pill exceeds the permitted delay and unprotected intercourse has taken place in the days before or after the missed pill, emergency contraception may be necessary.
It should be considered promptly: levonorgestrel up to 3 days, ulipristal up to 5 days, and a copper IUD in situations where it is indicated.
In case of doubt, a pregnancy test can be taken 21 days after the missed pill, according to the recommendations of the Assurance Maladie.
A missed pill is not a mistake. It is a contraceptive situation to be managed quickly and methodically.
Medical information: this article provides general information and cannot determine the appropriate course of action for a particular pill. In the event of a missed pill, check your contraceptive's leaflet and quickly ask a pharmacist, doctor, or midwife for advice, particularly after unprotected intercourse.
