ER doctor gone crazy?


So went to the ER today because I just wanted someone to tell me I was okay in person. I’m new to town and my insurance is currently on hold while transferring over so I can only go to an ER. I’m about 4 weeks and 3 days give or take a little and the doctor said that she couldn’t see the baby so she thinks I have lost it... wtf?? I haven’t had any bleeding and only a couple dots or brown discharge so far. Also the lady doing my ultrasound said everything looked good and it would be way to soon to see a baby. She says my hcg levels are very low (they are 157) everywhere I read that kinda average right now so 🤷🏽‍♀️ I called my doctor back home who said it’s normal as long as they are Doubling every 2 to 3 days. She freaked me out so badly I was balling and the nurse when she left proceeded to tell me that she was telling me the worst case scenario. I just don’t know what to think anymore. Anyone have any information about this or work in the med field? Please help!!
