Im 1st time mom and 28weeks preggy. Im having sharp tummy pain like gastric or food poisoning pain. I guess must be my constipation. But the pain got worse and ibwent to KKH and doctor said no early sign birth so sent me home with just paracetamol and 3 days mc. Today mc over but the pain is very sharp. Standing, bending, pooping its very painful. What is it.. gas or food poisoning or what. What sld i do.. been 5 days already.
