Extremely sore breasts and nausea each month before period starts..

 I have extremely sore breasts 10days before AF I was actually sick today at 1 pm this happens every month also get mid cycle cramping! This is my 12 month of TTC i had a day 21progesterone test back in June it came back with a score of 54 so thats good.. Tomorrow I'm going for a fsh LH and progesterone test! For the past year iv had the sore bread thing with sensitive nipples... I never used to get this! Everything always points to poss preg but then my AF starts! Could I have a hormone imbalance?? So frustrated
