Some womens numbers don't always double. It doesn't definitely mean anything bad. Your numbers are great for 5 weeks.
They say they should double in 48-72 hours so your numbers are right where they should be.
Your HCG numbers are just fine. What were your progesterone numbers? (usually, they are done together)
Thanks guys for the support I just got my third number and its a 3675 at 49 hours later. so I guess im still doubling just around 60 hours. I have a tv ultrasound tomorrow morning but the doctor says its possible they will.not hear a heart beat for another week or so.
