Please help .. Butt cramps !?

Did anyone has period pains & sharp butt cramps in early pregnancy?! Like around 4 weeks before the missed period

I’ve been having cramps since I tested positive 5 days ago and a few days before that . It’s not a sharp pain In my tummy more so a dull ache in the lower part.

To me it’s sound like my period is about to start & im going to have another miscarriage. 🥺🥺🥺
