20 week scan jitters!

My 20 week scan is in about an hour and my nerves are on edge right now. I haven’t been seen my baby since 8 weeks and 6 days and all kinds of impossible and possible scenarios are going through my mind right now. I also have anxiety over the sex of the baby because I’m surrounded by girls in my family and I’m guilt-fully hoping for a boy! I honestly can’t picture myself with a daughter. I have two daughters by association as I call it through my S.O. We need a boy in the family 😉

Thoughts? Advice? Limericks?
