Has anyone gotten a BFP after 12DPO

Arolynn

Today is CD 35 and I am 12DPO. I started testing every other day starting on the 20th of Dec when I was 9DPO and I got all negatives. AF was supposed to start yesterday but never showed up. I had period like cramps around 9-10DPO and thought she was on the way but nothing. I also have no PMS symptoms other than my breast are extremely sore and I have some slight nausea and extreme fatigue. I'm gonna get a blood test tomorrow, but I was wondering has anyone gotten a BFP so late? Like 12-14DPO?
