Hi, it's Karri. I have been on and off of here numerous times in the last 2 years with 8ish losses. I have another BFP and I am trying to stay positive, but man is it tough. I had betas drawn Sunday (15 DPO) and today (17 DPO) and the values were 73.8 and now 130. It's almost double, but not quite so of course I am terrified. I know I have to just relax, but I haven't had good luck and I was just hoping that the numbers would double and my mind would be at ease. My doubling time is about 60 hours. I did read on one site that 31-72 hrs for doubling time is fine if the hcg value is less than 1200, but I have always heard 48 hrs or less. I am just curious if anyone else had HCG values that didn't quite double and if things turned out okay. I have to go back Friday for more labwork. Thanks for your input.
