Cervical mucus and ovulation

The mucus produced during a menstrual cycle can give the best clues to when a woman is ovulating. Together with using ovulation kits, recording the changes in mucus during a cycle can help you maximize your chance of getting pregnant. Cervical mucus can be dry, sticky, creamy, egg white and watery.
If you do become pregnant, by getting to know your body's signs and knowing when you ovulate, a women can use the pregnancy due date calculator to estimate the birth date of the baby.
Dry
The first few days will produce no mucus, indicating that conception is not possible at this time.
Sticky
The next stage you will notice a sticky, white mucus. When pulled apart between two fingers, the mucus will be sticky but breaks easily.
Creamy
As the cycle progress, mucus becomes thicker and creamy looking and increase in volume ten fold. it feels similar to lotion. With the finger test, it will stretch further, but still break as they are stretched completely apart. There is a chance pregnancy can occur at this point.
Egg white
During ovulation the mucus becomes thin, stretchy and clear, like egg whites. This is the highly fertile period. Volume will continue to increase until ovulation reaches it's peak. This egg white mucus provides an optimal environment for sperm, allowing them to live for 2-3 days in the women's ovum.
Watery
The last stage is the watery cervical mucus. It's wet and maybe stretchy. chances of ovulation are markedly low.
It might take a month or two before you become familiar with your cervical mucus. You'll also need to keep in mind factors that can make interpreting cervical mucus difficult. Certain medications, like antibiotics and cough medicines for example can change the nature of cervical mucus.
