Ay mama, importante talaga na makipag-ugnayan ka agad sa OB mo tungkol sa cervix at ang tightness ng tyan mo, hindi dapat maghintay pa, lalo na kayo is that far along na. Ang tightening you're feeling could be Braxton-Hicks or something else, at kailangan i-check ng doctor para sure ka na lahat okay with baby. First time moms kasi sometimes worried kami kung normal ba lahat, pero that's exactly what your OB is there for, to give you peace of mind at real medical advice tailored sa case mo. Strength to you mama, almost there na!
