Anxious about movement or lackthereof

Tina
I'm 24w today (woo!) with an anterior placenta. For the last two days I have been so anxious about how much baby is moving or not moving. I typically feel him various times throughout the day, but it's almost always when I'm sitting and still but sometimes not even then. I keep freaking myself out that there might be something wrong when there are big gaps of time when I don't feel him. Rationally, I know that because he's my first AND I have an anterior placenta, movement is going to be less obvious at times. Can anyone else relate or have any words of reassurance?
