I was having lower abdominal cramps but not like period cramps before my scheduled period. I was 4 days late on my period. When I started it started out pink then bled for 2 days then went back to pink for a day and stopped. My period is naturally 6 days and kinda a lot heavier than what it was this month I'm worried I'm pregnant but it is to early to take a test so i would just like opinions to know what to expect.
