Numbers Doubled!!

When I went into doctor 12/31 my urine came back negative. I had peed an hour before my appointment cause I couldn’t hold it. Plus, I’ve been drinking lots of water! We assumed it was diluted. Got blood work and doctor said my level was low for where I was supposed to be. It was 71. I was supposed to be 5 weeks. She assumed I got pregnant a week later. Now assuming I was 4 weeks. Got my bloodwork back from 1/2 and it’s more than doubled and she said it was a perfect number for where I am at! 193!! I’m so relieved. Got my first ultrasound 1/26 @ 7 weeks 3 days! I feel finally relieved and hopeful!
