Implantation or ovulation cramps

I had unprotected sex the 13th & that’s the day my ovulation started.. prego rate was at 11%

I’m not on birth control or anything..

I have weird cramps as if my period is on the way, wanted to know if anyone else has experienced this.. & if it’s too soon for implantation cramps. It’s mostly on one side

Btw I ain’t trying to get prego.. give a sister some advice Im panicking
