All women are at risk of becoming pregnant, even by taking the contraceptive regularly because their effectiveness is about 98%. In addition, the use of antibiotics or other medication may decrease the effectiveness of the birth control pill, increasing the risk of pregnancy. See some examples of medications that can cut the effect of the birth control pill.
Other situations that may limit the effectiveness of the birth control pill and lead to pregnancy are:
- Changing your contraceptive and do not using condom in the first 2 weeks;
- Have episodes of diarrhea or vomiting within 3 to 4 hours after taking the birth control pill. In this case, one should take a new pill or use a condom;
- Forgetting to take the birth control pill at the same time;
- Forgetting several times to take the contraceptive pill during the month.
If you forget to take your birth control pill in the first week of the package, there is a higher risk of pregnancy because ovulation can happen earlier and the sperm can survive for up to 7 days after intimate contact.
If the woman thinks she is pregnant, but is still taking the pill, she should take a pregnancy test as soon as possible. If the pregnancy is confirmed, the woman should stop taking the pill. The use of the contraceptive pill does not change the outcome of the pregnancy test nor does it harm the baby, but should be stopped once a pregnancy is discovered.

Is it possible to get pregnant while taking the pill and breastfeeding?
The Cerazette birth control pill, which is used during breastfeeding, helps to prevent pregnancy and is about 98% effective as other birth control pills. However, if the woman forgets to take the pill for more than 12 hours or takes an antibiotic, for example, she can become pregnant again, even if she is breastfeeding.
