Has anyone had negatives early on and then actually been pregnant?

My period has been exactly regular for two years, never more than a day late. It is now 8 days late. I took a FRER on the second and fifth late day; both being negative. Neither were with FMU but I feel like after five days late it would have at least had a faint line in the middle of the day if I was pregnant.

I’ve been pregnant before several years ago (miscarriage at 6 weeks) and at that time I had cramping and fatigue and I craved beef which I don’t eat. I’ve been cramping for over a week, sleeping longer than normal, and wanting hamburgers.

What do you think? Is it just late from stress and I’m reading too much into the symptoms or could I still possibly be pregnant?
