Making myself CRAZY

Courtney • 37 years old, married with stepkids. BFP with 🌈 after first IUI and due October 2017!
I have dreamed I got a BFP two nights in a row. For the last two days I've been exhausted. Early to bed and naps! I tested today and got a BFN. Here's my temp chart (didn't temp for a day)... Anyone think there's still hope?
