Camps/not ovulating?

So I've been having on again off again cramping in my lower abdomen and back since Saturday...I am 99% sure that I ovulated about 7-8 days ago. AF is due around the 1st and I usly don't get cramps until 2-3 days before, so this cramping is waaay early if it's AF showing her fangs...on a whim I went to the dollar tree and bought a bunch of pregnancy tests and a few ovulation predictors. I took an ovulation one tonight to see if maybe that was what this pain was and I was off on my cycle but it was negative. My boobs started feeling sore today as well which is unusual...to anyone who has been pregnant before, could this be something or am I just symptom spotting like an addict? I have zero experience with pregnancy as my mom was very closed about it with my younger siblings and I have mostly male friends...my one friend who has a child didn't even know she was pregnant for a long while so she's no help in this early stage! Thanks in advance for anyone who reads and comments, I appreciate it :)
