If I’ve been taking the pill for a week …

….. and had sex on ovulation day is there higher risk of being pregnant? He ejaculated inside me

When someone starts a new hormonal method of birth control (like the pill) they need to use a back up method (like condoms or practicing abstinence) for one week before that method will be effective.

After that first week, the hormones will be integrated into the body and can help prevent pregnancy up to 99% (even if ejaculation occurs in the vagina) when taken correctly. In order for the pill to be effective, a person needs to take the pill every day at the same time.

So if you waited a full 7 days, there would be protection as long as you were taking your pill at the same time. If the unprotected sex occurred on or before the 7th day there would be a risk of pregnancy. If this is the case, Emergency Contraception is an option which can be taken up to 5 days after the sexual contact but is more effective the sooner it is taken.

It is also important to know that unless someone is practicing the natural family planning method, it can be extremely difficult, if not impossible for someone to know when they are ovulating. A doctor would need to advise someone and how to do this method correctly.  In addition to this, most birth control pills work by stopping ovulation all together.

Remember, while the the pill helps reduce the risk of pregnancy, it does not reduce the risk of STIs. Only condoms and dental dams can.
