Is it normal to feel like baby dropped and has barely moved? I'm 30w 3d

It felt like he just dropped last night and walking around this morning, I noticed he looked lower than before. Husband noticed some too! And now I havent felt him move but a few little thumps here and there. I had a drs appt yesterday and he wriggled and moved for her and his heart rate floated between 130 to 140 (as usual). He seems fine but its wierded me out some🤔
