Yes. Mine was positive at 13 DPO. Negative until then

It is very, very possible to get a positive after 12dpo. 14dpo should be the day your period arrives if you're not pregnant, so at 14dpo a home test should be most accurate. But even then, sometimes the home tests can't pick up on the hormone for another week or even two weeks!My advice is to wait until 14dpo to test again. If it's negative, take another test at 17 or 18dpo if AF doesn't show up. Then keep testing every day or every other day after that either until AF shows up, or you get a BFP.Remember, as long as AF doesn't show up, there is still a chance you are pregnant. Don't lose hope!

Got a very faint positive at 13 DPO.
