How do you know when your fertile? and what's comes first , ovulating or being fertile ?

Chicken or egg: To be naturally fertile you need to ovulate. If you have regular cycles you ovulate about 14 days before menses. This is when you are most fertile. You can buy ovulation kits at the store and test for this to maximize conception.

Ovulation timing: The optimal time for conception is 48 hours prior to and up to the day of ovulation. Therefore, start having intercourse a couple of days prior to when you actually ovulate and have intercourse every other day for a total of five times to help ensure sperm are there when you ovulate.
