AF due on December 7th. Anyone else?

Hey guys I'm so so nervous right now. Af is due on 7th I'll be so scared to test because I don't want a bfn. This cycle I've used the sperm meets egg plan and it's says if af dosent show 15 days after ovulation to take a test. So instead of testing on the 7th I'll test on the 8th. I'm hoping for the best I want my Christmas bfp so badly guys you have no idea! I've had two miscarriages last year and have been trying for my rainbow baby for a little over a year now and being pregnant would change my life!! When are yall testing?
