Was feeling baby a lot & now I’m not?

I’m 22 weeks pregnant with my 3rd. I’ve been feeling baby since 16 weeks (posterior placenta), but right at 20 weeks I was feeling baby every day pretty consistently up until recently. Now it seems like I barely feel him.

I know they say not to do kick counts until 28 weeks but it’s just kinda freaking me out.. I don’t really remember going through this with my others since they both were anterior placentas & I didn’t even feel flutters until closer to 25 weeks with them.
