I have regular cycles 25 -29 days, and I am on my period 5 to 7 days with day 2 to 4 being extremely heavy. So heavy if I don't have to go out I stay home and I'm usually having to change underwear/bedding (sorry tmi but I wanted to paint a clear picture). A few days after unprotected sex in November around the time of suspected ovulation I had cramps, twinges, urge to urinate. 4 days before my cycle was due to start I began spotting (pink/Brown). I spotted until my cycle started on December 4 but it was light. Stayed light the first few days then what I'd consider medium throughout. Oh I skipped an important detail, took a pregnancy test day before I was due it was negative. Anyway I stopped bleeding on the 11th but on the 12th started spotting again. Spotting stopped on the 15th. I was due to start this cycle January 1st. Between now and then I have experienced waves of nausea, very swollen/sore tender breasts at times, painful cramps, fullness in my pelvic region, dizziness. It's now Jan 4th and still no period. Cycle day 32. I have not had intercourse since the time in November 21 & 22. Is it possible that I'm pregnant? Also having an increased amount of vaginal discharge ranges from cloudy but slimy to white and creamy. Due to symptoms I did STD testing about a week and a half after intercourse and it was negative. I'm confused!
