Over the last few wks I have noticed a lump appearing above my belly button when I try and sit up. When I mentioned to my midwife, she very casually told me it was my abdomninal muscles seperating and to take more care sitting up-now I'm freaking out!! I'm only 22wks and can already feel about a 3 finger wide defect between my belly button and my sternum, and its now spreading below my belly button as well. Presumably this will only get worse as I get bigger. This is my 1st pregnancy (in case you hadn't already guessed). Does anyone know how bad these things get? If it will get better on its own once the baby is born? If it will come back (and be worse again) with subsequent pregnancies? Should I go back and grill my midwife more or is my GP the best person to speak to???? So many questions!!! Please help as despite a scientific background I still can't help having visions of my belly splitting apart or ending up permanantly like Jabba the Hutt after the birth.
