It could be a number of different things. I had the same problem with my first boy and turns out he had kicked me so hard (around 30 weeks) that he had torn a ligament in my side! I would definitely call if it gets worse though!
Hm. I'm just about 30 weeks as well. Lol. Maybe it's just a bad week. I'll definitly call if it gets worse. I just hate to go back up to the hospital again. Haha.
I get it sometimes too. Its usually when she decides to kick around in there. I had a sprained rib literally like a week before I got pregnant so its still a little sensitive and it seems like that is where she likes to hang. That and beating the cr*mp out of my belly button. Its very strange my first never did this.
i get a lot of pain in my belly button area whenever the baby is around it....i swear sometimes she is trying to push it out from the inside...its very painful...i have asked my doctors about this on a few occasions and they all have said it has to deal with the position of the baby....
when i get the pain i try to sit down, put my feet up and eat popcycles until she moves off the area...sometimes it takes falling asleep to get her to move though
