Implantation cramping?

Sh

Hey there y’all! I have a quick question about ovulation and cramping. - I had sex on the 25th of February and then ovulated on the 1st. I cramped So so so much on the 1st and it was mostly lower stomach and hip pains.

If I wait till 10DPO will I get an accurate test reading? Sex was unprotected. What are my chances of pregnancy? Would implantation bleeding come pretty soon? Or does it happen past 10DPO?
