Has anyone else experienced lapse in movements early on?

I’m 16 weeks 1day, at the beginning of 15 weeks I started feeling movements (second baby), OB confirmed they were movements because she could feel/hear him flip away while checking for heartbeat with the Doppler. He started moving frequently after that. Now I haven’t felt anything noticeable for two days. I’m trying not to panic because it’s still early, I’m just not used to this, I had an anterior placenta with my daughter and didn’t feel her until 20 weeks. Has anyone else had this when they first started feeling movements?
