I keep getting this horrible stinging/ burning sensation at the very top of my belly/bump. At times it almost feels as if it's a pulled muscle, but today it has been really painful & much more constant. It almost feels as if it would be contractions, but I don't remember having contractions from This area during my 1st pregnancy. Does anyone know what this could possibly be? My physicians office doesn't have a 24 hour contact service so I'd have to wait until Monday to call.  Any advice or input is greatly appreciated! Thanks!
