neg test but still pregnant?

How many people get bfn and still end up pregnant? I am 12 dpo and one day away from period. And i know for a fact i ovulated when I did. I normally have cramps and soreness and other symptoms to show my periods coming and i have NOTHING. But I do have this hightened sense of smell. Everything smells horrendous to me! One night i made my husband take a shower before he laid down in bed with me cause he just smelt so bad for no reason! Temps are still up high. No drop yet. But negative tests!?
