Less movement but still moving


Do yall get concerned if you feel baby move less? I'm 31 weeks and usually my baby is super active seems like all day. But the other night she had a weird movement that felt different, ever since then her movement feels very shallow and less often. I have an anterior placenta so I thought maybe she is balled up behind there because I dont feel her in my ribs any more. At our last ultrasound she had both of her legs up in front of her face so maybe she just went back to that position? My doctor said as long as I feel her within 4 or 5 hours then she is fine, but I can't help but be worried...

Here is a picture of her with her foot in her face lol
