OPK Help

This is the first time I’ve used anything to track ovulation. My cycle length is usually 26/28 days so I began testing on CD10 to be safe. I know it is ideal to test around the same time every day, twice a day, but I’m still getting in the groove of everything. Should I start seeing darker test lines soon? Any advice?

My Glow calendar is in the comments. I’m also taking OLLY prenatal vitamins and Conceive Plus Fertility Support. TTC baby #1 with my husband so helpful tips are welcomed 🧚🏻‍♀️✨
