Mama, please call your OB or go to the nearest clinic/hospital today, hindi dapat mag-wait kung may contractions ka kahit na-settle na, lalo na with diarrhea at 27 weeks pa lang. Better safe than sorry talaga, kaya contact your doctor agad, okay? Alam ko nakakawalan ng gana ang false labor, pero yan ay kailangan i-check ng professional mo para ma-rule out kung may something else. Sending you strength, and please update us once you've seen your OB!
