Okay, so I took a test on the 22nd and it came back positive. I did it with my first urination of the day. I took another test a week later in the late afternoon and it was negative. My scheduled period isn't due until the 5th of October (28 day cycle) and I've always had a normal cycle. I started bleeding unexpectedly on the 29th of September with a much heavier flow than usual. I've also noticed that there are clots/tissue. I am worried that if I was pregnant I am no longer so. Also my pelvic area has been bloated... almost bubble like. It's firm but not rock solid. I only had cramps the first day the bleeding started. Any help is welcomed.

You don't take a home pregnancy test in the afternoon. It HAS to be done first thing in the morning the first time you pee... or a negative is very likely until you are fairly far along.
