I have been on trinessa for about two months now. I am about to finish my second pack, I am on the the third set of pills which are dark blue.

For three days, Wednesday to Friday (December 17th to 19th), I have had unprotected sex with my boyfriend. I had finished my period on December 15th, a Monday. My boyfriend ejaculated inside me for the three days we had unprotected sex. I have been taking my pills on time everyday. I am just a little worried because I don't actually know when I am supposed ovulate, so I was wondering if I could have gotten pregnant from that. I have also experiencing a brown colored discharge and I dont really know what to think of it. Should I be worried?
