Hi girls, thanks for responding. I tried to post again here in response to your posts earlier today, about 5 times, but there must have been a problem with the site.

Ann Good luck!!!! I hope you are one of the 30%. Can you do a preg test early if you haven't taken any meds during your cycle?

Bec G, I'm so glad your 4th FET transfer worked. Will you be trying again?

I spoke to a nurse at my clinic today, and she said my success rate may not be as high as 30%, as my embryos were frozen 4 years ago, using the techniques they had then. She said 60% survive the thaw, so that will leave me with about three, and they would pick the best one that hopefully gets to blastocyst stage for the transfer. So, I don't know, it looks like out of 5 embryos, there will be hopefully one for transfer with a less than 30% chance of succcess. The logical part of me says it's not even worth trying, but the the other part of me says I've got to give them a chance.
