Cramping

Bekah • 27 and married, mom of a 5 year old son, and a 1 year old girl, soon to be mommy of sweet baby number 3!
I'm 24 weeks and have been having period like cramps for about 5 hours now... This is my second baby so I know these are not contractions. My dr said if it gets worse to head to the ER.. They are not getting better but not super painful either. Anyone else?
