Dehydration.....

Holy crap. I woke up in the middle of the night DYING of thirst like I had just drank a whole bottle of wine or something the night before. I haven’t drank since New Year’s and hubby and I have been TTC. Is this a sign of pregnancy? Sore boobs, fatigue, hot flashes and backaches. I have 11 more days until my “period”. Hopefully it’s a BPF instead. Anybody experience this?
