I m havind sever pains in my ovaries I m 20 and have had my period since 11 but I started on 11/01/15 and now today which is the six I m having I lighter flow then I did just a few days ago which I should even be on my period anymore because my periods only last 4 days usually but I stopped bleeding yesterday so I thought it was over but today I started bleeding again so I inserted a tampon and not even 2 minutes after inserting the tampon I started having really bad pains in my waist and I m scared can you please tell me why I have never had this pain at the end of a period before.. Although I did just stop taking birth control 6 months ago (menastrin) can this just be me getting back to normal or could it be something more serious than that?
