I got on birth control pills, and then 10 days after, my boyfriend were fooling around without a condom and he put himself in me, only for about 5 seconds, and then he withdrew completely. We are usually VERY careful, and since then, I have been FREAKING OUT because I know a woman can get pregnant if there was any precum. I am now a day late for my period, but I don't know if it's because I started on birth control and my body is getting adjusted, if it's due to stress, or if there's a good possibility of me being pregnant?

Slim but possible. Take a pregnancy test.

Very possible it is a combination of the stress and the pill. You have to chill out. Stress will most likely cause you to be late.

Everything worked out fine... took a pregnancy test, it came out negative and then my period came an hr later!

That's good to hear! Now you just need to relax :)

Okay so the period lasted heavily for 2 days... and then really light/ brown for 3 (sorry about too much info there... ). Do you think its because of being on Yaz, or do you think I could still be pregnant? I just want this ordeal to be over!

Yaz
