I had my 4th and final beta yesterday. The levels rose from 808 on Monday to 2596! The nurse said things looked great and we scheduled my ultrasound for November 28th. I will be 6 weeks and 6 days at that point so we should see something! I'm feeling a little better and a little less nervous and as I've seen those numbers rise. I think a heartbeat will really calm my nerves. I just feel so grateful that this is happening.
