The hardening of your belly is typically a Braxton hicks contraction, which is nothing to worry about. Your body is preparing to go into labor which is good! If it is accompanied with bleeding, strong pain, leaking of fluid, or you have several in short periods of time then I would call in.

I heard 2weeks early is that bad..

what does it mean when ur belly get hard

It really depends on how early.

It is bad to go into labor early because babies organs could not be fully developed. The closer you are to your due date the better

yeah I heard

in some cases it could be potentially dangerous.
