No Dip Before Ovulation- Normal?

Amber

So when I do the charts like mine feature on fertility friend I never see any charts that actually look like mine, and almost all of them show a pretty significant dip the day before ovulation, not the slow rise that mine shows. I know I haven't been testing long enough (thermometer came way later bc weather) but I haven't seen any with this rise that I had, and it's making me nervous tbh.
