Aww Willow . I wish I could make it all better for you. I'm sure they are just doing tests as a precaution, like you said, you and your DH have good sized heads so it is most likely just hereditary. You poor thing having to stress about it until Monday. Make sure you keep yourself busy so you're not thinking about it all the time. I hope your DH spoils you tomorrow for Valentine's Day, you deserve it!
