From what I have read on the internet, there are some ovarian cysts that secrete hcg, but they are very rare. I would think if your number is doubling appropriately and the doc knows about the cysts, everything is on the right track or he would tell you otherwise!
Stay positive and keep us posted!! :)
nope, an ovarian cyst can't cause a false positive : ) sounds like its the real deal! CONGRATS and i'm hoping that you have wonderful numbers today! good luck! we'll be waiting for an update!!! tons of SSBD!
