If you take the number of days of your cycle and divide it by two you will get a general day for ovulation. So if your cycle is 28 days you would normally ovulate on day 14, but this could change each cycle. My cycles are between 24 and 28 days so I ovulate earlier around day 11. You will have a clear sticky discharge around the day you ovulate. Normally it is a lot of discharge. You can get a basil body thermometer and take your temp every day when you wake up. Read the instructions on the thermometer and it will tell you how tell when you ovulate if you do not have the discharge.

Ovulation does occur before menarche. Menarche is the term used to describe a girls first period, menstruation will only occur if the woman ovulates. With that said some people will experience vaginal bleeding as a result of hormonal imbalance which will look like menstruation but without ovulation occurring beforehand, and sometimes we call that menarche - because we've no way of knowing if ovulation had occurred.
