What does ovalating mean?

Answer 1

I think you mean ' ovulating' , note the spelling.

A female of the species, be it human or other mammal, ovulates in a given menstrual cycle.

For human it is approximately 28 days. For other mammals it can be shorter /lomnger in time.

At the point in the female cycle an egg is released from the ovary and passes into the fallopian tube. It this point the female is ready to be fertilised. This is the point of ovulation/ovulating. Once fertilised the 'egg' will pass into the uterus/(womb) to allow the foetus to develope. for a period of 9 momths for humans, to the birth date.

Like a womens menstrual period comes once a month, the point of ovulation also comes once a month, but at a different time in that month.

Answer 2

It means your body's released an egg. So you can get pregnant if you have unprotected sex any time tween then and when you have your period when your body gets rid of the egg.
