Please Help......

Okay so I'm really freaking out and I really need advice. I'm 32weeks and I haven't felt my baby move for about a week. I mean I kind of feel really really faint movements but that's about it. Im so use to him doing somersaults and flipping all over now nothing. I use my Doppler just to be safe and find babies heartbeat immediately but I'm still pretty worried something is wrong. I've done everything to get him to move from drinking cold water to drinking something sweet and lying down and still nothing. Should I go to the er or just wait till my appointment on the 3rd?
