Mine wasn't a hard feeling this time. First kid it kinda was
I wasn't skinny skinny ,and yes you start to feel a hard area where the baby moves up and is starting to develop a few cm under the belly button.
I was touching my lower belly laying down and i have just a slightly discomfort when I touch it I just feel like theirs a hallow space!! It's really messing with my mind lol
I'm having the same problem and I'm 16 weeks, is it painful at all for you if you put pressure? I get some pain when pressure is put on it and when I cough.
