Mama, please contact your OB or go to the hospital na para sure na okay lang ang baby mo, 34 weeks, mas safe na i-check agad ng doctor para walang alala. Abdominal pain in the third trimester can be normal sometimes (Braxton-Hicks contractions, round ligament pain), but they really need to rule out anything serious, kaya huwag maghintay pa. Let me know how you go, ha? Sending you love!
