No one believes me

I know I sound crazy but something as a mother tells me that something is wrong. I am 20 weeks pregnant..I haven't gained a pound (I've actually lost 5 total), I am overweight prepregnancy (BMI 33), I don't look pregnant in the slightest, i had some spotting a few days ago (which the doctors I called werent concerned about at all) and I haven't felt our baby move in a few days. He's already on a schedule I swear. I've done all of the tricks and I still can't get him to move. I can't find him on the doppler either (I'm a nursing student I've gotten pretty good at this). My fiance doesn't think anything is wrong. My doctors don't think I have a reason to be concerned, but my intuition says that something is not right. Idk what to do anymore. Advice? Ease my mind? Am I crazy?
