Hello, my last normal period was on August 25. I had unprotected sex (without ejaculation ) on the 29th or 30th. I took a Next Choice the next day but because of my bulimia I purged two hours later. A week later, on September 2nd our condom slipped off, but there was no ejaculation either. I took another Next Choice on the fourth of September, this time I kept it down. Four days later I got what seemed to be my period (from the next choice, I presume) and that lasted for about four or three days. An online website calculated that my next period should arrive on September 22nd according to my last period (August 25) but I have yet to have gotten it. I know Next choice can delay my period about a week, but it s now the 29th and I still don t have a period. I think I got the stomach flu on Sept. 11 and have been feeling nauseous, stomach aches, and headaches . But I m also worried I might be pregnant. Would it be too soon for all of that if I was? I still have nausea from time to time, its not very intense but its a bit of an annoyance. And yesterday as I wiped I noticed something like a blood clot, or a burgundy mucus with some very slight brownish discharge. Could I be pregnant? I took a pregnancy test two days ago and they both turned out negative, so whats going on?
