PMS or PG?

Katie • TTC for three years with hubby.

My boobs have hurt, felt swollen, and se HUGE (nothing different, happens before AF)... but for the past week i will wake up at 3 a.m. quenching for thirst and not be able to go back to sleep... also, I have been eating like food is going out of style!! (Odd cause when it's hot outside I usually have no appetite)...

AF is due on Saturday.
