My af was due on 8/10

Ok well as I said AF was due on 8/10 and I have been experienceing a cramping and bloating feeling for two weeks now. Along with some breast tenderness and discomfort.

I haven't had any spotting but I have been having a lot of discharge especially today was a heavy amount. And the last time I had sex with my so was around my ovulation time (according to glow) 7/26. And I've also started taking prenatal vitamins. I just would like to know what y'all think
