14 DPO, AF due today, BFN

Hey all, just wondering what my next step should be? Yesterday I used my last FRER so wasnt going to get another one until 15DPO, so I just used the 88 cent this morning and it was BFN. Wish I knew what was going on in there. No cramping which I hope is good because normally I do before AF. What would your next testing steps be? This may sound super silly, but I was hoping if I am pregnant I could get a BFP before November 21st when I get married, so I can surprise my husband during the first look. Otherwise it's back to trying on the honeymoon. Thanks for any advice!
