Could this lump I get on my stomach be baby or a hernia or something else? Wondered if anyone else got this too. I get this going from a lying down position to sitting up slightly. Maybe it's completely normal, just haven't seen any other pregnant bellies like it before.
Does it kind of cone up in the middle? If yes it means your abdominal muscles have split, it's called disastis recti, fairly common i think. Happened to me too, mine still haven't quite knitted back together post birth
Definitely looks like diastasis recti. Your abdomimal muscles are in two strips joined by connective tissue. The pressure of growing baby can weaken the tissue and cause seperation of the abdominals. You should try to minimise as much as possible any actions which result in the doming as it can make it much harder to get your muscles back together after delivery. Instead of sitting straight up roll on to your side and use your hands to push you up rather than abdominal muscles.
