Gigantic boobs period 3 days early help

Ma
My boobs got bigger every day since the day after O, areola look a tiny bit bigger. Got a cramps and twinges, then 6-7 dpo big time liwer back and ovary / sides cramps.. I REALLY thought that was IT ! And was planing to test on Monday! But here they come ! 3days early  AF full blown but not like usual, heavy brown and came out right away, my boobs are still huge and still feeling queasy .. Am I tripping ? 
Am I just confused with pms ? 
But I never had a 25 days cycle, the past few months I was always 2-4 days late .. 
Anyone can relate? Pregnant or not
