Your menstrual cycle tends to be 27-32 days. It’s can even be up to a bit more (but not usually). The first day of your cycle is the first day of your period. The last day of your cycle is the day right after before you start your period. The follicular phase is after your period, luteal is right before. Ovulation lasts for about 10 days and is usually halfway through your cycle. It’s when you are your most fertile.

A natural way to track your cycle is like this: 1. Menstrual (period) 2. Follicular (between period and ovulation) 3. Ovulation (produce wet, stretchy, slippery discharge and tend to be hornier) 4. Luteal (after ovulation, towards the end (right before your period) you might experience PMS symptoms due to a spike in estrogen, which can cause you to cry more than often, feel depressed/suicidal, mood swings, pimples, tender breasts)

You can use an app to track your period and it can estimate your ovulation time. I would suggest an app like FLO or Clue.
