Baby Movements 29 weeks

Today I've been a little worried. I've felt my baby move/kick maybe 6-7 times this whole day and that's very unusual for her. She's normally moving/kicking 5-10 times a hour. Should I call my OB or wait until tomorrow when I have my appointment? Yesterday I was moving a lot, i started getting the room together for her and last night she was real low, her movements were all in my pelvis. Then today, there's barely been any. I've tried laying on my left side, I've walked, I've ate, I've drank juice and water, I've ate some mints. I don't know what else to do.
