Plz help!!!!!

I have been feeling light cramping in my lower abdomen for about an hour and a half. I went to the bathroom and I checked my cervical mucus, at first it was white/creamy mucus. When I had a bowel movement, I checked my cervical mucus again, I had a little of clear and streachy mucus. Am I near my fertile window?, Near ovulation?, Or am I ovulating?
