I am only 30 weeks pg and have had pain in the stomach from late last night all day today. The pain is constant, doesn't come and go and feels like muscle pain (??pulled AB muscles) or stomach ache? . I paged my OB and he thinks it is muscle related as it is around the belly button?

Has anyone heard of this before or experienced anything similar?

I didn't get Braxton Hicks with DS #1 so don't know what it feels like.??

Worried!!!!
