Did i get the dates right and have intercourse at the right time?

The only time you miss the egg is during a period, ovulating just means that it's dropped down, othewise making it easily accessible. You can get pregnant at any time even when you're not ovulating. Ovulating lasts 3-4 days. A sperm can live inside you for 2-3 days waiting to fertilize the egg. Keep in mind just cause you have sex during ovulation doesn't mean you're gonna get pregnant the first or second time. For some ppl they get pregnant, other ppl (like me) takes a few months of trying. As long as it's within a year you have nothing to worry about, if it goes over you can always consult with your doctor about any concerns.
