You ovulate before your first period.
Then your egg is mature and can be fertilised.
Fertilisation is when a woman’s egg merges with a man’s sperm.
So you can get pregnant.
Many girls and women do not notice when they ovulate.
This might be the case for you.
Ovulation always happens before your period.
And even before your first period.
All girls have vaginal discharge before their first period.
The vaginal discharge shows that you will soon get your period.
That might be in 1 month or 1 year.
Some girls notice the vaginal discharge.
Other girls do not.
So you should use protection.
The best option is to use a condom.
A condom also protects you from sexually transmitted diseases.
