Anxiously, I hope it all went ok.
Well....I think my body's playing tricks on me. Good news is, my lining did improve - it went up 2mm in just 3 days so it was 6.5mm at CD13. Pretty good given my history of thin lining issues. Nice triple layer too. So I'm not sure if it was the estradiol that I've been taken the past 2 days that gave the boost. So theoretically, at this rate of growth, my lining should hit 8mm by ovulation on CD15.
BUT, my leading follicle that measured 9.5mm on CD10 couldn't be found. The doctor thinks that it had regressed, and I won't be ovulating at all this cycle. Either that, or the improbable scenario where I actually ovulated on CD13 just before the scan. It's improbable because we wouldn't expect a 9.5mm follicle to mature in just 3 days unless they had some kind of supernova growth.

I did ask if the estradiol supplement could've caused regression but the doc doesn't seem to think so.
So...looks like we've found a solution to my lining issue, and we just need to make sure the other half of the equation works properly as well. Am going to ask the doc to give me Femara to boost follicular development, and add the Viagra and estradiol for the lining. Never tried this combo before so at least it's something new. Then I'm going to request to transfer my 5 frosties over from my previous RE. If my lining and follicles are both looking good, then I may request to thaw those 5 frosties and culture them to blast. If they don't make it, we'll do an IUI. If the cycle fails, then it's on to fresh IVF.
Sounds like a plan?
