30 weeks tomorrow, baby not moving much

I have an anterior placenta this time around so I don’t feel her move a ton like I did with my son, but I usually feel at least one crazy 30 second kicking session a day with little kicks here and there throughout the rest of the day.

It’s currently 11:45pm & she’s barely moved all day. I can’t really recall any kicks. Just little feelings as if she’s shifted a little or something, but nothing like usual.

I’m not one to worry most of the time, but what should I do? What are the really good tricks to get her to move?

If she doesn’t move, what should I do?
