my gf and I had unprotected sex. I was sure that I did'nt ejaculate inside her. She took two birth control pills within five days. Now she started bleeding almost 10 days earlier. Is there a chance of pregnancy? Or it is just a side effect of pill.

Hi, Anon.

Thank you for your post.

Did she take emergency contraception or regular birth control pills? The early period is likely from the pills she took. If she is having her period (bleeding) she is not pregnant. If she doubts this, she can test for pregnancy.

For future, use protection to avoid this kind of situation.
