I'm 23+5 and I've all of a sudden got this horrific ache in/on my belly, to even touch or lift my belly if that makes sense?

When I sit I get shooting pain down below right into my stomach at first I thought it was because I held my pee in for so long but I don't think it's that?

I genuinely feel like I'm having labour pains of some sort, baby is still moving away but when I feel him kicking/moving it's all of a sudden really sensitive

The pain is literally all over my stomach not anywhere specific, to touch my belly button and anywhere around hurts to 'lift' my belly hurts too I am struggling to sit/stand without pain and turning in bed is near impossible just because of the sore belly any ideas or similar experiences?
