Movements

Hi, I'm 20.6 weeks. I had my scan yesterday and I am having a boy! He wasn't moving much and was squeezed into a small space. I had to go for a walk and have some food so they could do measurements.

I was concerned as I hadn't felt any flutters but on the weekend I felt lots of strong movement. But yesterday I felt nothing and today nothing. I checked the doppler today and I had the scan monday so everything looks fine. I am just concerned that I finally felt something and now I can't feel anything!
