@sami.massie, sperm can live for 5 days, and it just depends on when you ovulate. You can get cheap testers off amazon.com, and I like the easy at home brand if you’ve never bought any before.
@sami.massie, apps use the average of women that have similar cycles. When I went off the app it was wrong for my actual ovulation. 🤞🏻 The app is close for you.
