Hopeful - Uch!! I'm so sorry.
I wish they were able to tell you more about the embryos so you can better plan for next time. Why did the charge you the full amount for the FET if they didn't even end up doing a transfer in the end?
I'm really glad you are taking clomid this month as it is really hard to feel like you are not doing anything. And maybe you'll get lucky.
I know it feels like it will never happen, but one day you'll be holding a baby and it'll be all yours!
Also, what is a "WTF" appointment?
They keep on changing my protocol, but every month my lining sucks. Now my RE just wants a 6 mm and she'll transfer. It's so pathetic. They have no idea what is wrong with me. I don't have any of the "typical" lining issues - endometriosis, poor circulation, poor estrogen receptivity, or endometrial scarring. I just randomly have thin lining. I am getting another blood work-up done tomorrow to see if anything more can be understood and will be getting an endometrial "scratch" next week to see if maybe that can help. Also she is starting me on a PCOS-specific multivitamin. We'll see what happens.
Maria - Welcome! Good luck with your transfer. FETs are much less likely to be cancelled than fresh cycles, but it still could happen. Basically, with FETs, they only care about your lining and minimally about your hormone levels so that they are in the right zone to sustain a pregnancy. My FETs keep on being cancelled because my lining is garbage. Each time it has been too thin. (Thin lining is a really uncommon problem with cycles, unless you have endometriosis, so I wouldn't worry about it if I were you unless your doctor tells you its a problem for you.)
