should I be worried if she has not moved today?

not necessarily, sometimes we are so busy throughout the day we don't really notice. try drinking something sugary and eating something and moving around. if she doesn't move before you go to bed you might want to call your on call doctor just incase

Try drinking some orange juice or eat some candy and see if she moves sometime afterwards.

thank you and this is my first kid and I'm 29 weeks

drink some ice cold water. eat something

that's what I'm doing right now and still nothing

then yes you should be worried
