I missed my period two months in a row, now that I've finally got it, I've been having off and on severe cramps that wake me up out of a dead sleep from how painful the are, also my period blood was extremely heavy at first, I'm on day 6 and it lightened up quite a bit but the whole time my period blood has smelled very foul, I thought I may have forgotten a tampon up there but I checked and nothing. This has never happened to me before.
