Someone please help!!! Please answer

I’m entering the 3rd day in my fertile window and my cervical mucus has been light, white and stretchy and I have know gotten a brown dry discharge. I’m experiencing really bad stomach pains on the side of my stomach near my belly button, on my lower stomach and under my rib are these normal ovulation cramps?? I had sex exactly a week ago right after my period ended and iv been a little bit bloated but my breasts aren’t tender sometimes they are a bit sore but not much. I’m just worried cause I rarely gets bad cramps during this window sometimes I do but mostly just before my period I do. Could something be wrong?? Can someone please help and tell me if this could possibly be early pregnancy because I’m stressing out!!!
