Cramping everyday after ovulation

Chloé

So I had sex on 10/10 and my ovulation date was the next day then I had sex on the 12th. From the day I had sex til today I’ve been having dull cramps. I’m 7DPO but not spotting just headaches, backaches, and cramping. Has anyone had these symptoms and ended up having a big BFP when taking a preggo test?
