The nurse called just a few minutes ago. Saturday's results were 19,391. Sunday's results were 28,256. She said my doctor said "this is good." According to most websites, including this one (https://www.americanpregnancy.org/duringpregnancy/hcglevels.html) the levels should double every 48-72 hours. These tests were only 48 hours apart, so I am feeling pretty good right now! UPDATE: THIS particular website (https://www.betabase.info/showDailyDoubling.php?type=doubling&multiples=Single&bucket=14) made me feel even better about not doubling yet. I read that the higher the hcg levels, the longer it takes to double. This confirms it! I have a scan scheduled for Monday night at 6:10pm. We will be 7wk1d when we go for this appointment. Please keep us in your prayers to see a healthy heartbeat next Monday!!!
