So for two weeks I've been experiencing normal pregnancy symptoms. I calculated that if I am pregnant I'm 4 weeks 6 days today. On this Tuesday, 5 days before my expected period and 11 days after my last ovulation and intercourse, which I guess I was 4w 2ds along I had pink spotting which has never happened to me before that so I assumed that was implant bleeding and my suspicion was confirmed by multiple sources on the internet. But the day after I had a normal period like flow, but it was brown. It's been decreasing steadily and becoming becoming more red and I believed it had stopped yesterday which was the third day, but I started red spotting today after about ten hours of nothing, is this my period and I'm just being paranoid? Is this just abnormal ib? Or is there something serious going on here? Help!
