Needing some guidance!

I have taken the ovulation tests for about 3 months now and I've NEVER got a hard read like today. I would change up when I would start testing by 2-3 days bc my periods range from 30-34 days and AF is supposed to be debuting on Saturday. I took a pregnancy test and it was negative... Could I potentially be early??? I am having some fatigue, spotting, nausea, diarrhea (sorry if it's TMI) and slight cramps. I would LOVE a BFP but I don't want to get my hopes up. Let me know what you ladies think!
