Breast tender/AF not due for a week

Tara • 02.22.16 ZJLA Baby #2 is on his way!!!!
My breast have actually grown 2in!! Could it be??? (I measure only to track weight loss lol) but today I took my bra off and it literally felt like bricks falling to the floor. Then I looked down and felt them and thought they looked bigger. My husband agreed. So I measured them to see and they have grown! 
​I've also been drinking a lot ALOT of coffee lately (trying to study for a test). I drank 4 cups plus an energy drink and STILL took a nap. 
​My ovulation date was last week. AF isn't due for another week. 
​What do you guys think!??! Wishful thinking??
