Is sitting for long time dangers for SHC?

Ay

Hi

I have to do my job online and have to sit for 2 hours !!!! I never experienced SHC and it’s quite large compared to my 5 weeks sac! It’s measured 7*4*13 mm.

Is it dangerous to sit for long time?

I’m so terrified!!! I don’t want to lose this baby too. :(
