How long after your missed period did you get a BFP?

Hi all, my hubby and I have been ttc for 3 mos. now. I'm 2 days late for af and my breasts itch and every now and again they feel tingly or slightly sore. I'm having some slight tiredness and mild nausea. I took a test this morning and it was a bfn. I've never had any issues with my cycle before nor have I ever experienced breast itchiness. How long did it take for you to get a BFP after a missed period? And what were your early pregnancy symptoms?
