When should you worry

Lindsay
So I'm hoping some of you girls can ease my worries. I'm almost 33 weeks and I still feel my baby throughout the day but I get in my head that it feels like decreased movement... Like three days ago was a really active day and since then I feel her but they are light movements and not as frequent as that one day so I sit here just getting more worried but okay so what I should call the on call doctor and go in l&d? I've already been in there twice because I worry and I feel dumb like oh here's that girl that comes in here all the time and worries... So I'm basically asking do you other pregnant moms notice these decreases in movement?
