Strange question belly pain

I’m 12 weeks 5 days pregnant but this after noon every time I stand up from sitting I get this weird pain. The only was I can describe it is if you was to squash a sponge and it slowly go back to shape. I when I stand up it feels like my belly is slower at stretching out? 🤷🏼‍♀️🤷🏼‍♀️ hard to explain but worried it’s not normal? Like above my belly button really.

Any advice appreciated thank you xxx
