Old OPK reliability

Leah

They've been sealed, but arent showing lines for little while (like 3 minutes instead of 1). Now giving a positive result 2 days ahead of what my typical schedule would... I don't track cm. Should I go off them or typical schedule.

Back story, using a private donor and would like to let him have his usual schedule if I dont need him. Thankfully he's great and we've already met up the last 2 days.
