Im 33 weeks and towards the later half of the day my stomach seems to get tighter and tighter, which seems to start causing discomfort around my belly button (mostly just above and to the left) it's always quite hard around that area so I'm guessing it's baby's head or something but the main problem is that when I laugh, cough or sneeze or even just try to get off the damn couch it's incredibly painful. Like a really sharp pain as if there's no space for my stomach to contract or stretch or something. Has anyone else had this? Is there anything I can do to stop it happening? Currently lay on my back on the sofa as any other position is really uncomfortable, feels like only way to stop the tension in my belly! :/
