I'm 19+3 pregnant and today whilst at work i suddenly got stomach pains. Hard to describe the pain, but was like a gripping, cramping pain. It's still quite painful so has been consistently aching for about 10 hours now. I saw myself in the mirror and i look huge! My stomach feels firmer too. Is this possible that my stomach can suddenly grow so much at this stage in such a short space of time? And is it possible that the pains are just growing/stretching pains? I have a scan on Friday but just wondered if this is usual.
