I had this and went and got monitored. It was just pains. I was 34 weeks. Now I know unless i have tightened stomach coming and going its not Braxton hicks.
My doc just said that it's the baby on ligaments or just on nerves. It's normal I've been having it since 32 weeks I'm now 37
Im about to be 35 weeks tomorrow and for me sometimes i have a really sore belly for a few days and when she does kick in a certain spot i get sharp pains. It normally lasts a few days and then goes away
Call your Dr if you're really worried. I'm 34 weeks and haven't been feeling that
