Andrea--
I am also a worrier like you and married to a "non-worrier". It amazes me how my husband can sleep anywhere anytime no matter what is going on. Sleep eludes me because I always have something on my mind. right now it's 4:35 AM and I've been up for an hour (typical). I have a cancer dog who is not doing well and my dad is having problems too. If it wasn't that, it would be something else.
Anyhow, glad your latest "problem" was minor. I'd love to say, "put your worries aside" but I know that's not easy for worriers to do. But try to put them away for awhile and get on with that "embryo transfer" --
Take care.
