I GOT MY BFP!! Why sooo early though?? AF is not due til 9/15?

Wow we have almost the same cycle. My LMP was 8/14 and i have a 31 day cycle, so AF should be here monday. I'm 8dpo and i want to test so bad now! CONGRATULATIONS on your BFP, Have a happy and healthy pregnancy. Please send me your lucky vibes, i really need them. Xoxoxo
