“Could I be pregnant?”

I am almost 3 days late for my period, I usually always have a 25-26 day cycle, I don’t think I’ve ever been more than a day late before. For the past 5 days, I have been having mild/moderate cramping (not as bad as menstrual cramps). I woke up the last 3 mornings feeling like I’m about to start my period any minute, but nothing. I took a test one day after my missed period but it was negative (I took it in the evening, not sure if that makes a difference) I should also note that I had unprotected sex on or around my ovulation date. I am not on any form of birth control. My last period was November 2nd, 2021. Did I test too early? Is it normal to have consistent cramps for days leading up to a positive test?
