Numbness during ultrasound?

Cheyenne

Yesterday I had my complete pregnancy anatomy ultrasound (I'm 19 weeks). During my ultrasound my entire right leg and foot fell asleep and I couldnt get the tingling to go away until after I stood up. Could it have just been that baby was on my sciatic nerve? Or did it have to do more with the way I was laying? Has anyone else experienced this?

Here's a picture of my sweet babe just for attention 😍💜
