AF due 6/17 going crazy!

Ugh! This is my 2nd month TTC #1 and i feel like even though i tell myself not to over analyze every symptom i do it anyway! I had a temp drop the last 2 days and one of the ladies here told me either AF is coming or it could be implantation. The only symptoms i have are sore bb's and nausea. I wish there was a way to know sooner! Oh, and i slept for 6 straight hours the other day--totally not like me. Trying to stay hopeful. Any words of encouragement?? Anyone else want to walk through this week with me?
