I dont know what to think this month

We went on vacation during my fertile week and I missed two days temping. We also went from the east coast to the west coast then back. I did temp when I woke up but they all seemed kind of low and stayed low up until CD 21, 6DPO. This morning I gained a pound over night, have horrendously painful breast with some pretty dark veins showing and have waves of nausea that makes me scared to even take a breath for fear that I would throw up, yet dying of thirst ALL DAY LONG for the past 2 days. I know it could All be symptoms of AF coming or could be something more exciting... just ready for Saturday to come around! Been TTC for 7 months now and I am ready!
