Hay, sis, that rib pain in pregnancy is SO common, pero since you're already feeling it, please mention it to your OB sa next visit or call them now if it's really bothering you, okay? They need to check if it's just the normal pregnancy stuff or something else. A few of us moms experienced it around that time, and our doctors had different advice depending on ano ang cause, kaya importante talaga ang check-up. Praying it's nothing serious!
