Hi Belle! That's so great that your lining got thicker, I just recently started acupuncture again so I hope I have a good result as well.
We definitely never thought we'd even be considering IVF this quickly, but we've had a couple doctors suggest that route after three rounds of Clomid/Femara because I'm 36 and my FSH is 12.4. Most everyone says it's not for #1, but planning for any subsequent kids we may want to have. My AFC was also on the lower side at 11, so with those two numbers plus the two CP, I really think it may be an egg quality issue and IVF is the option that will give us the best chances and most peace of mind.
We also live in the heart of Silicon Valley so I can't help but feel like people are much more blasé about IVF here.
