Im 33wks and I dont feel much movement. But they sent me in for an ultra sound, and they told me that my amniotic fluid is high for the amount of weeks I am, so it stops me being able too feel the movements so much. Also if babys head is down, then there is less movment, because the movments you feel are done with babys feet.
If you are in your third trimester, I would talk too your doctor, and see what s/he says.
last week, at 23 weeks, I hadn't felt my baby move for 3 days..Which was unusual for him because he was always so active..So I called my doctor since I was freaking out, and she told me I could go to the er to check on everything if I was reallly worried..So I went and they hooked up the heart monitors and we heard the hb, very strong..I got an ultrasound and it showed him moving around in there, I just couldnt feel it..
The doctor there told me that before 28 weeks, you shouldn't worry too much if you don't really feel anything..But after that you should keep track of movements..
Well I hope that helps a little, take care!
