Mama, yan na maaaring Braxton Hicks or just normal pregnancy pains, pero since 37 weeks ka na at masakit talaga ang puso mo, better go to your OB or maternity clinic today para ma-check properly, hindi ito dapat i-guess lang. Ang mucus plug ay hindi laging sign na ngayon na talaga, kaya kailangan mo ng professional assessment para sure. Isama mo na rin yung partner mo or someone you trust para peace of mind both of you. Keep me posted, ha, worried din kami dito!
