Hey, I need help. I'm 17 and have no idea. I started birth control 3 months ago (shot) and it stopped my period. I go in 5 days to get it the second time. I haven't had my period since before I started it so a few days ago and just had VERY light blood, it's was brown and clumpy. So light I didn't even need tampons or anything. I woke up this morning cramping super bad and the blood is still brown and clumpy, but there's a little more. Is this normal? To not have it for long and it be like this?
