My boyfriends birthday was coming up on the 8th, and although I notmally do not take birth control, I took 3 yazmine after looking up online that it could delay the process. I still started, but it was light. Yesterday we had unprotected sex, he always uses the pull and pray and so far it has worked for four years. During intercourse yesterday I started to lightly bleed again, and since then the only blood I see is light and watery, only appearing when I use the rest room. We were not rough. However my stomach is nauseated and my left side hurts . I've had a headache for about three days and after yesterday I feel extremely sick, fatigued and confused. It's almost like water, and it only happens when we have intercourse. I had a missed mc, d&c in december. Is there any possible way that these symptoms could be pregnancy related, since I only took yazmine the 7th and 8th of this month snd haven't used them at all since last March? Are there any other reasons for this?
