Mama, rib pain is pretty common sa pregnancy, maraming mums sa circle ko nag-complain nito around 6 months when baby's taking up space!, pero kung ganyan kalayo ang pain every 10 mins, mas maganda mag-check with your OB to make sure lahat okay lang. Could be positioning, could be baby's kicks, pero better safe than sorry, no? Your doctor will know what's best para sa iyo. Hang in there!
