Constant period pain?!?

Jennifer

I’m 38 weeks today and since yesterday I’ve had a constant cramps that feels like my period is coming. It hurts pretty bad, nothing I can time and honestly haven’t had many bh contractions to begin with. Just curious if anyone else has experienced this? Or any suggestions to what it is and what I can do? Also have been going pee every 10 mins just had a urine test Friday so no uti there
