Braxton hicks

Sooo im abt to be 31wks in two days. I always saw ppl who werent as far along as me talking abt braxton hicks. I never experienced anything like it so i just assumed i was lucky & wouldnt experience em! I think i was wrong. Pretty sure i started experiencing them super early this morning. & boy its a PAIN. If its braxton hicks man they hurt so much. Hope thats what it is though! & not something i should worry abt
