Uy, mama, any vaginal pain kahit saan ka man should really be checked by your OB, better safe than sorry, lalo na at 29 weeks ka na, kaya please schedule or call your doctor right away, okay? A few of us mums have felt different things during pregnancy (ligament stretching, baby position changes), pero only your doctor can tell kung normal lang or may need for attention yan. Huwag mag-worry alone, text or call your OB clinic, yan ang best move. Praying you and baby are both fine, sis!
