Is this normal?

I’ve been getting positive pregnancy tests since 10 dpo. My period was supposed to come yesterday and it didn’t so I took another test and it was positive. I have had a vaginal like cramping since Sunday. I have taken 8 tests (excessive I know) and they have all came back positive including a digital. I just want to know if this cramping is normal bc I usually get this type of cramping when my period is going to start.
