at 15 dpo they were 138 then 17dpo 452 then 22dpo they were 4594 then they stopped and did an ultrasound. only one..
I had my HCG levels taken at 12 dpo (days past ovulation) and 16 dpo. Numbers were 50 and 550! I think my numbers tripled. I think as long as they are doubling every 48-72 hours, you're good to go. There is a broad range of normal-high. What were your numbers?
I haven't had to get my HCG levels drawn - as my previous pregnancy was normal and healthy - so the doctor didn't try to draw it.
I think that if they are going up fast - it is a good thing though.
