Think I'm out this month

Af due in 3 days and I've been cramping like crazy. Sigh** I'm tried of trying and tried of putting myself thru heartache after heartache. I find myself just wanting to give up and I get so mad. I'm tired of this monthly torture of peeing on sticks, waiting for that magical positive ovulation test, trying to time everything, using preseed, propping up my hips ahhhhhh! I just want to scream! I'm devastated. I feel like a failure of a woman. We were created to conceive babies and I can't even do that. Fml
