I had unprotected sex on the 8th of this month (came directly on not in vagina). I figured my period would start on the 15th because it did the month before and its usually close if not on the same day. I had unprotected sex on the 12th (came inside) and my period started the next day(13th). Making it a 26 day cycle. It started off light pink then became red. It was heavy and lasted for 2 days. My periods usually last 4 days. The 16th I had unprotected sex and began bleeding. I figured it was just from my period just ending. That day and the next (17th) when I wiped it was light pink. 17th and 20th unprotected sex (came inside). 20th started having white discharge (8th day of cycle). I figured I was ovulating although I ve never noticed before. discharge became lotion like throughout the week and now its chunky. I believe I have a yeast infection but think I could be pregnant also. I ve been having cramps, nausea, diarrhea, increased appetite, constipation, gas, headaches, hiccups, and bloating. Started taking azo yeast (28th) but don t want it to harm the baby if I am pregnant. What should I do?
