Hello, I had unprotected sex 2 nights ago with my boyfriend. Im 18 years old and Ive been on Triquilar birth control pills for about 5 months now so I didn't think not using a condom this one time would be a big deal.

After sex my boyfriend told me he came just a little bit and pulled the rest out away from me.. The next day I had a light pink/red discharge which later on in the day turned brown, is it possible that I can be pregnant?
