3 days late for the first time ever- negative pregnancy test 😩

Hi everyone,

I am currently 3 days late for AF, have pregnancy tested twice, yesterday & today, and both tests have come back negative. I have never been late for a period- except in the case of my 3 children. Each of those 3 times, the tests came back positive from a day before my missed period. I am SO confused. We haven’t been really ‘trying’ to conceive, but we haven’t been careful either- few baby dances during my ovulation window…

I’ve been having cramps/heavy & stretchy feeling on & off over the past 4-5 days, but other than that, no real symptoms.

Is it possible that I am still pregnant, or, is this more likely a freak missed/late period? Thoughts? Thanks Xx
