I had protected sex with my boyfriend on October 23rd and he didn't even come, but I'm concerned about something else. If perhaps precome were to come into play and some of it had gotten inside of me, could I have gotten pregnant? My breasts are very sore to the touch, I have slight clear nipple discharge from one of them, and I'm having very sharp pains where the nurse practitioner said my right ovary is. She said the pain could be an infected fallopian tube or ovarian cyst and prescribed Flagyl to treat it. I have irregular periods, so I don't know when my next one is or when I ovulate. I took an EPT brand test November 4th and it came back negative. Then I took a First Response test November 11th. It also came back negative. I was wondering, am I worrying over nothing? Could I be ovulating? Or is it a huge possibility that I could be pregnant?
