PLEASE HELP- LONG POST SORRY- My doctor seems clueless..

A little background; LMP December 12th. 3 weeks ago I started getting EXTREMELY hungry despite being on diet pills (I’ve stopped taking those) and some fatigue. Been nauseas for a couple of weeks. The past week and a half a wave of symptoms came - crazy sense of smell, vomiting now with nausea, extreme fatigue and hunger at times, acne, pretty much all the 1st tri symptoms. Took a test last Wednesday and got my positive! It was slightly faint but definitely there. I called my OB, they set up a ultrasound and appointment for this Tuesday based off my lmp and ordered blood work. Thursday my hcg was 26 and progesterone was 19.1 (which seems high?). Re drawn hcg on Saturday and it was 141 (went up 5.5X!!) my symptoms, especially nausea and vomiting has gotten so much worse over the past few days too. SO TO THE POINT- my OB’s nurse called me today and wanted to reschedule my ultrasound and appointments for tomorrow because based off my hcg I’m only 1-2 weeks. I called them back and explained 1. I have multiple sclerosis and have an infusion in a week, I have to know how far along I am and will not be canceling my appointment. Also 2. I’ve been having all these symptoms for weeks and V/N for a week now which usually doesn’t start until 5/6 weeks and 3. Technically 1-2 weeks you aren’t even pregnant, your body is getting ready for ovulation. Also I tested again this morning urine and my test line was darker than the control so I know my hormones/levels are going way up! Please tell me what you think, when we’re your first symptoms, am I crazy? I am going to go to this first ultrasound and then switch docs immediately..
