Nervous

I had a miscarriage in January at 16 weeks. I’m almost 19 weeks pregnant and felt flutters and movements weeks ago but haven’t felt anything in a long time. I have my anatomy scan August 1st. My 16 week appt was good and baby girl was healthy and growing and good heartbeat. I’m worried because of the movements though. Well lack of movements...this is my 3rd baby. I should be feeling them right? Especially if I already have weeks ago.
