Ovulation help

Kaitlin

Good morning ladies!

My husband and I are on our 6th month of really TTC and I typically have a positive OPK between cycle day 14-16. This is the first month that I have been taking the test and I have a faint line that isn’t getting any darker and I am on CD 17 now.

What would cause someone to ovulate later than usual or should I be worried that I am not ovulating this month?

Thanks in advance!
