Oo normal lang yan at maraming nag-deliver ng Grade 2 placenta, kaya don't worry too much about that part, but honestly ang pag-ache ng pwerta mo is something you really need to check with your OB about kasi that's more pressing and they'll want to make sure everything's okay, lalo na approaching na ang due date mo. One of my mum friends had similar concerns at turn out okay lang, pero importante talaga mag-consult para ma-assess mo properly ang symptoms mo!
