Hi, I recently turned 20 and just 'finished' my period for the month...it stopped after about 8 or 9 days (regular for me), but then a couple of days ago, I noticed a little bleeding again. It's only light and there is no pain, I thought maybe it's just my body doing some extra 'cleaning out', so it is now technically the 14th day of my period- but again, it's light and there's no pain....should I be worried?
