So I supposedly started my period on valentines this year, but the "blood" was a dark brownish red for an entire 5 days, and I had some pms. I didn't get anything in March, but in April I got the exact same thing. Nothing for June, and July was a dark brown red but lasted a day longer and was a bit heavier. So in august, I got my period with actual blood and everything was normal. In September, all I got was 3 days of the same dark brown stuff. It's October and I think I should've gotten something but still haven't and I don't have any pms so far. What is this? I'm pretty sure it's my period but it seems so different. I only had actual blood in august. And do some girls experience little pls than others? I rarely have pms and I hear a lot of people have really bad cramps
