Horrible lower stomach pain

I’m 20 weeks and out of no where I have really horrible stomach pain right on my csection scar.

I had a placenta abruption with my first.

Nope not round ligament pain I know what that is and I drink lots of water. If I don’t feel better in the moring I’m going to call my doctor but is anyone else having this issue?

Also I have felt baby since14 weeks.... very very active and now not really moving. 😩 hoping everything is better than in the morning
