What does a hard belly mean?

Ari

Every so often my belly gets super hard.

Like on both sides across my entire lower abdomen (belly button and below)

No movement happens just rock solid.

Feel like it lasts for about 10-12 seconds until I massage my tummy and it slowly relaxes and gets soft again.

This feels different from a little area where gets hard - which I’ve heard can be the babys butt pressing against me.

This is my whole lower half abdomen hardness.

So odd!

Also I’m 20 weeks 3 days if that helps!

Thanks 😊
