Baby Moving

Okay so this might sound like I'm overreacting and I might be but I needs some opinion. I am used to my baby moving literally all day long like he's always moving. Drives my Dr crazy. Anyway. Yesterday he didn't move very much just here and there mostly last night when I got back from my trip and took a bath. He kinda went crazy for a couple minutes. After that I haven't really felt him move at all so it kinda freaks me out a little bit. Idk if maybe hes just running out of room or what. Not sure if I should call my Dr or not. Also I'm 29 weeks
