someone please tell me if i should go to the hospital to get checked

so i know back pain in obviously normal in pregnancy but my lower back honestly just aches and kinda hurts to even touch, then it wraps around and i feel like a have cramps too.

i’m scared it could be my body trying to go into labor or something since my mom had this problem around the same time too. it’s just no matter what i do my back won’t stop aching and when the cramps start it aches and it’s uncomfortable to even touch my stomach when it happens but the baby is moving around a lot as well. i’m 20 weeks and 3 days. does this sound like braxton hicks possibility?
