This might give you a ray of sunshine.
I have three friends who tried IVF for years. One in particular tried for ten years and mortgaged their house to pay for it......and all three with no success and much heartache. They all fell pregnant within a year of giving up. The ten-year lady now has three sons. She told me that falling pregnant is like finding love. You don't find it when you're looking for it....& then you stop looking & it finds you. It's things like this that keep me going on the darkest of blue days.

My beautiful Nan says "Don't worry. It won't happen if you worry." (She has 11 children...I think that qualifies her)
And I know I've read other posts here that tell similar stories.
As for me, I still haven't figured out how to stop worrying!
But I'm sure it'll stop eventually. I'll never, never, never give up.....but I'm trying to let go.
Happy, tranquil thoughts for you.
