Mild cramping on 7/8 DPO

Has anyone else experienced this? Is it a higher probability of AF than it is of BFP? 😔

Last night and this morning... I’ve gotten a trickling of mild cramps in the uterus area. I don’t get cramps during AF. I luck out on that. It’s usually just back pain and knee pains during AF. I know unusual but that’s how it’s always been.
