My period has lasted for over a month now, with a constant heavy flow. its so bad that whenenever I change my tampon, it will burst out after maybe 2 hours. This has happened before when I first started getting my period when younger but then I started having a normal cycle with no medication. Sadly, its hitting me harder then ever. I m only 20, so I shouldn t need to have my uterus removed. Would birth control help me?
