No movement yet? 19 weeks

mamaof3

I thought I felt some flutters around 17/18 weeks, but 19+2 today and haven’t noticed much in the last couple days. This is my second pregnancy, but first to make it this far. I have a posterior placenta, so that shouldn’t affect anything. Doctor said it could be later since it’s our first, but just anxious after our losses (twins at 17 weeks, mc at 7 weeks)… we did have a heartbeat check less than a week ago and all was good. Anyone else not feeling movement until later?
