New to ovulation testing πŸ€”

just took this and according to glow it says my ovulation day is the 7th. i know that if the test line isn't as dark as the control your not ovulating yet. But just wondering since it popped up does that mean I for sure do ovulate every month or does it just depend if both lines are the same color? I'm going to continue to take just new to this stuff πŸ˜‚
