Ovulation

Arillia

Hi ladies. Just need some advice.

I know Glow is a app. According to glow I am suppose to ovulate the 10th. Been ttc for 6 months, this is my first month using OPK’s.

Im currently on CD12.

I got my first visible line today. My question is, is it possible to only ovulate later in a cycle? Should I continue to test, or is it possible that I dont ovulate
