So, I lost my virginity about a week ago-  it was quite painful and i bled quite a lot afterwards and my vagina was stinging. The next day my period started or I just carried on bleeding and I've been using tampons. Last night I had really bad cramps and when I took the tampon out this morning there was a large piece of grey/brown flesh on it about 3 inches long and strangely enough there wasn't a lot of blood. I have been on the Depo shot for 2 months now and have been spotting for about two weeks. I thought it might have been my hymen but isn't it meant to actually come out the vagina is it? I thought it just tore. Any idea what it could be?
