Baby's movement

Mary

I'm a FTM and 29 weeks 4 days. I'm getting increasingly paranoid about my little ones movement and not sure what's normal and everything. I know about kick counts and have read things that if she moves at least ten times in a 2 hour period during the day that she's okay.

I have a very sedentary job sitting at a desk so I have alot of time to be able to feel her move and some days I feel her alot more than others and then I get freaked out when I don't feel her as much if she's less active one day but was more active the day before.

I also read that if I don't feel anything for 12-24 hours I should call my ob.

Is this just me? Am I over reacting right now? I just want to make sure I'm doing everything I should be and that she's ok in there.
