Fertile window (also called fertile period) are 6 days within your menstrual cycle that you can easily get pregnant. If you’re serious about getting pregnant or preventing it, then you must understand your fertile days. This is because intercourse during this time will get you pregnant.
What is fertile window?
Fertile window is the 6 possible days in your menstrual cycle that you can easily get pregnant. It is usually calculated with lifespan of the egg and sperm. Normal sperm has a life span of about 5 days. While normal ovum or egg has a lifespan of 24 hours. This means that if you have intercourse 5 days before ovulation, you can still get pregnant.
Your fertile window is therefore 5 days before you ovulate and one day after.
Some terms used to calculate your fertile days
Before we go into how to calculate ovulation and fertile days, let me explain some terms.
LMP (Last menstrual period)
This is the first day of the last time you saw your period. For example, if your period lasted for 5 days and ended on the 5th of march 2014. your LMP is 10th of march 2014.
This is the difference in days between 2 of your period. It is also the difference between 2 of your LMP. How to calculate you menstrual cycle? If you already know your LMP, then you have to wait for your next period. The difference between your LMP and The next LMP is your menstrual cycle length.
For example, if your LMP is 15th march 2014, and you notice your next period in 14th of April 2014, then your menstrual cycle is about 30 days.
However, the length of your menstrual cycle can be affected by emotional stress, drugs, chronic (long term) illness and academic activities.
Whats the normal menstrual cycle? If then length of your cycle is between 21 to 35 days then its normal.
Period or menstruation
This is the cyclical bleeding that comes out of your vagina every month. It is due to hormone changes in your body. Normal period should last between 2 to 7 days.
This is also a cyclical process during your menstrual cycle where the ovary releases an egg into the fallopian tubes for fertilization. If you do not ovulate, you cannot get pregnant.
When is my fertile window?
You already know your fertile days are within your menstrual cycle. So how can you detect your fertile days?
Your cervical mucus
The first day of your menstrual cycle is the first day of your period. After your period, your vagina becomes dry and then you will notice thick white discharge coming out.
As you get closer to the middle of your menstrual cycle, your thick discharge becomes creamy white or milky white discharge that is sticky and without smell. This type of discharge is not very fertile as it is difficult for sperm to swim through.
Just after your creamy discharge, your discharge becomes stretchy, clear, egg-white and watery. You can easily notice your discharge stretches between your fingers and does not break. This is your ovulation discharge and returns to creamy discharge or thick discharge after ovulation.
Your fertile cervical mucus that indicates your fertile days are
- Creamy white discharge (less fertile)
- Stretchy egg white (Fertile)
- Clear watery discharge (fertile)
Regular intercourse during this type of vaginal discharge can get you pregnant.
Basal body temperature (BBT)
This is another way you can check your fertile window. It gives you clue about when you’re likely to ovulate. Before ovulation, your body temperature is normal. Just before your ovulate, there is a dip in your basal body temperature. After ovulation and due to the effect of progesterone, there is a slight increase of basal temperature by 0.8ºF.
To be able to use your basal temperature, you should monitor your menstrual cycle for months. BBT is your body temperature at rest. It is done early in the morning while you are still on your bed before any activity.
However, it is only very useful after months of regular basal temperature charting.
Ovulation kits and fertility monitors
Ovulation kits is used to predict when ovulation will occur due to surge of luteinizing hormone (LH). During your menstrual cycle, LH surges and reaches its peak about 12 hours before ovulation. A positive test means you’re likely to ovulate soon.
Also, the fertility monitor can predict your fertile days for about 5 day prior to ovulation. Though more expensive, it is a non-invasive way to easily confirm you fertile days.
