Af due October 20th anyone else around that time

I'm due for AF on the 20th. I've been having cramps here and there and horrible headaches done nausea at random times I suffered a mc in August and my obgyn removed scar tissue from my previous csections from around my ovaries she said I should have better luck getting pregnant now. I've had sex everyday this month because me and the hubby have fun with it. So I hope I get lucky this month!
