Every pregnancy is different :) that is for sure lol. My first 2 I had very bad round ligament pains and with my 3rd I didn't and then this pregnancy I don't really have anything of symptoms, its like I feel normal but excpt the pain now that I'm having.
I just thought it was weird because I never felt this pain with my first baby. And I had a full term baby.
Im 29 wks also and I have the same pains. A friend of mine said its most likely your body getting ready to have the baby.
Your hormones are trying to relax everything down there and it could also be baby pressing down on the pelvic floor too. This is my 4th baby and since 28-29 weeks I had that and from then on I still get it every day now, I'm 34.1 weeks pregnant.
