Glow Precentage

Lori
I'm new to Glow, I'm 25, married for almost 2 years and we are ready to start TTC. I started Glow a couple days before AF and I've been logging information every day. My fertile days are coming up. Is there anything I can do to raise my percentages? Right now my best day is at 33%. Is that good? Also any other tips would we welcome!
