<s>[INST] Ive been on birthcontrol for two years. This past Friday I had unprotected sex after missing two days of my pill. I know for a fact that my boyfriend ejaculated inside of me. The next day I took my birthcontrol and started having dark brown, almost black, discharge. Its been three days since we had the unprotected sex and i am still discharging a lot. Is this something to worry about? [/INST] Hi, Well missing two doses and having unprotected sex seriously increases the chances of you getting pregnant. What you need to know is that a brown discharge is normally not something to worry about, but a brown discharge around 4-5 days after having unprotected sex can be because you have conceived and are now pregnant. As such take a home pregnancy test to make sure. I hope this answered your question. </s>
