Veteran OPK & BBT Testers- Did I ovulate?


I am usually pretty regular with my cycle in terms of OPK and temping (I ovulate anywhere from CD 19 to 25 though). I’ve been testing this go around for 4-5 months, and I tested for 9-12 months (or more even), with my last. So I feel I’m pretty good with the tracking. But this month has thrown me off. Temps are overall lower, and never got a true positive OPK (for me- I always get a super dark line, way darker than the control, not just equal). But I had some cramps, and a temp jump. What do you all think?
