23 yr old female 5'4 160. this month I have had two periods. the first one i got on the 1st of january and it was very light i barely bled out. then on the 28th i got the 2nd one. this one started out with dark brown blood and was mildly heavy but today it got a bit heavier. i am also experiencing cramps and feel very tired and uncomfortable. I am worried because i have never had a period twice in one month and because i have had a miscarriage before.
