This mornings OPK

Am I right in thinking when you get your peak you ovulate 12-24 hours later? According to my app I have my peak. The other half is working when he finishes work we have an appointment with the bedroom 😂 so will we be fine to wait till this afternoon?

Would you say it’s my peak? My Femometer app says peak, but being first cycle using OPKs I’m not sure how dark they are supposed to get? Glow says I’m due to ovulate tomorrow.

These two were this morning the photo below was 10pm last night.
