Confused

I used this glow app to fall pregnant last year and now my little boy is 2 months old and I'm using it again as a method of contraception. What I've noticed is that when choosing the "trying not to conceive option", it doesn't show my ovulation and "dangerous" days in red like it used to before I tried to conceive. It's only showing my periods and predicted periods. I'm not sure if it's because I've only just started using it again about 3 weeks ago or if it has changed? Can anyone help me?
