Movements changed

My baby’s movement has changed the past couple days she’s been lazy. 20 weeks and normally she is up for HOURS. I can feel her every kick. And now she barely does- still kicks throughout the day but has slowed down a lot. Practically overnight.

I had my anatomy scan today and she was great! Heartbeats great everything looks good. OB wasn’t concerned.

….But why has she gotten so lazy the past couple days out of nowhere? She was literally non stop 24/7 moving before,

Anyone had this happen?
