Did you know that women's ears become more symmetrical when they ovulate? It's true!

1. Ovulation is the process by which a woman's body produces and releases an egg to be fertilized by a sperm cell, leading to reproduction.

2. Women are born already bearing the total number of eggs that they will ever have in their lifetime.

3. Oral contraception works by preventing or disrupting the processes of ovulation and fertilization.

4. An egg lives for only four to twelve hours once it has been released, waiting to be fertilized.

6. Or you can read your cervical fluid.

7. And sometimes you can feel it happening.
