Opinions needed!!

af was due Friday or Saturday Thursday in the morning I was sure that beezy had showed her face however only bleed in the morning Friday I spotted a couple drops and nothing since then. This morning in the shower checked my Cm and no blood at all but it was the same as it would be at peak ovulation. I took a frer this morning got a bfn but it was after about a half pot of coffee (pee was diluted) I will test again this afternoon and first thing in the morning I am almost sure I am pregnant I have had a headache for a week now. just wondering if anyone has ever experienced the same thing? MERRY CHRISTMAS AND BABY DUST!!
