24 year old white female. I had unprotected sex with my boyfriend and then used the morning after pill 48 hours later. Additionally, I am on ortho tri cyclen lo and take it at the same time every day. I was two days late for my period, which was lighter than usual. Now, two weeks later, the last three instances of sex with my boyfriend has resulted in small, noticeable amounts of blood coming from my vagina . Is this an indication of pregnancy?
