For the last 4 years I have had a "normal" period. They have always happened at the beginning of the month and always lasted no longer than 6 days. Well I had my "normal" period this month but then i had another one 9 days ago. i should not have my period until the 3rd. I'm still bleeding but now only spotting. i'm still having cramps and slight back aches. Am i having a miscarriage and didn't know i was pregnant or is this normal?
