I am now 41 weeks pg and my bump has started to look funny. By that I mean it looks like a normal baby bump from the top to my belly button and then underneath its a bit wobbly. In the wobbly bit though there is a bit that is rock hard and a bit tender to touch, it feels really strange and was just wondering whether it was something to be concerned about? The baby is moving more so now than in the last couple of weeks so I'm not concerned on that front, just that this bit at the very bottom is rock hard and a bit sore. Think it is possibly muscle but not sure.
