(call me weird but im a person who dreamas about my period the night before, so i dnt get ANY PERIOD PAINS OR SYMPOTOMS prior a period)

and then in april i got my "period" . usualy myu period is HEAVEIR on the first 2 days. but this months it was extremley LIGHT! and then got a bit heaveir. but i just though noo, its just cause im stressed. and then in May i got a period. it was LIGHT to for the first 2 dyas and then it was LIGHt again for the last 2 days.. as i have mentioned before my period has only got on for 5-maybe 6 days but usuali stays at 5. but on this monthg it went on for 7 days!!!
