Ok so a few weeks ago I got the worst cramps of my life that came with back pain and it was a few days before my period then comes the time my period is supposed to start I’m 2 days late and that’s not normal for me I start my “period” but it’s super light like don’t even need a tampon light (that’s what I use for my periods) and it stops like 2-3 days after and has little to no dry blood when normally I have a heavy flow that lasts 3-5 days I’ve also been feeling nausea and been having diarrhea and I feel different I have been for a while like around my belly botton area I just feel strange ?
