16 weeks - felt movement but not anymore

I’m 16+6 weeks pregnant today. The last few weeks I’ve sworn that I’ve felt one of my babies every now and then. Maybe once or twice a day if not more. Well the past few days I have felt absolutely nothing. I’m assuming that it’s probably normal but I still get worried.

I’ve had 3 miscarriages and my mom lost my brothers twin at 4 months. She also miscarried a second set of twins.

My next appointment is Friday.. trying not to worry too much until then.
