When I was younger (around 16-17) I would capture really strange periods that would be really sweet and last longer than usual. That last for quite a while and I get on the depo shot for a year or so, it helped regulate my period and whatnot, but ever since I've been bad the shot, I don't normally achieve periods. I do every once surrounded by a while, but not too often.
Lately though, for the recent past 6 months or more I get cramps and adjectives that junk that comes along next to periods, but I don't usually acquire them either, I did this month, but I usually don't.
Not sure why it happen, and I don't have vigour insurance to get myself checked out, but I seem to be to be alright..
Maybe if you've been on any type of birth control, that could be why?
