Vix - I'm sure everything will be okay. There is still plenty of time for your lining to thicken The FN told us it depends on the level of estrogen in your system. It will continue to increase as estrogen goes up apparently.
I found a link that you can get some good natural remedies to help thicken it too. DF uses some in tea - red clover, nettles, raspberry leaf. They may be worth trying?
I'll have my fingers crossed for you! When do you have your next scan? sorry if you mentioned it. I'm on my phone and can't see your post now!
Two girls, one dream and baby you are it!
