Labor pains

I feel like a may be experiencing some preterm labor pains but I'm not sure? I have back cramping like period like cramps not the ones before you start but during I guess if that makes sense? They arent full but not super intense. I'm not bleeding or leaking fluid but I'm not sure exactly how to time the cramps either. Babys are moving but my tummy isn't tightening crazy like with braxton hicks
