Hoping to get some feedback.. i am approx 4-5 weeks pregnant, my blood test on 2/9 was 2,052 we retested today 2/11 and my number was 7,633. The nurse was excited at first but i noticed her tone change when she realized i wasn’t as far along as she would have expected with those numbers. She was going to talk with the doctor and plan for an ultrasound next week. Should i be worried?
