Hi, I am 30 weeks and 5 days. I have had extreme rib pain for awhile that will not go away. It's like my muscles are being stabbed by something. I know rib pain is normal in pregnancy but I seriously don't think this pain is normal. I'm not bleeding or cramping so I feel like it's my body not baby. The doc prescribed me anti acids which haven't worked. I didn't think it was from that. Any suggestions?
