This is my first month using clear blue digital and I noticed it’s a blue dye on the test strip? Does that matter that it’s not red dye? Will it be harder to pick up a positive ovulation? I’m so worried I’m gonna miss it!! Please help!! I know testing for pregnancy a red dye is better but what about ovulation? I took a picture of my tests so far I’m on cycle day 10! The digital shows blank circles
