AF due 12/12

I'm hoping this is our month! I'm hoping to find a cycle buddy who's is experiencing some of the same symptoms. I've been pretty crampy ever since ovulation, which was 6 days ago. I've also been overly thirsty for the past three days. I'm a teacher, so I usually don't think to drink a lot of water throughout the day, but the last couple of days I haven't been able to quench my thirst! I'm not sure if this is a sign or not. Fingers crossed for a BFP! I'll probably test on the 9th.
