Ay, mama, importante talaga yan! Please see your doctor ASAP or go to the nearest clinic, diarrhea in pregnancy kailangan talagang i-check, especially para sa baby at dehydration mo, ha? One of my mum friends had something similar mid-pregnancy and the OB was really strict about it. Stay hydrated with water or coconut juice muna while you're waiting to see the doctor, pero seryoso, don't wait, iba ang pregnancy, kailangan ng professional advice talaga. Hugs, and please update your doctor na!
