First time using OPK? Faint Line?

Rushia

Hey y’all. This is my first time ever using an OPK..so it’s a very faint line. According to my app (and other apps) I’ve already had my ovulation day. Can you get a faint line after ovulation occurs? Im in my last day or so of my “fertile window”. Does this mean ovulation hasn’t happened yet? We have baby danced A LOT.. 🙏🏼
