understanding-ovulationWhat is ovulation?

Ovulation is the discharge of a mature egg from a follicle developed inside the ovary into the fallopian tubes. Most of the time, it occurs regularly, half way through a menstrual cycle. For example, if you have a 28-day cycle, ovulation is likely to occur on day 14. Once released, the egg can be fertilised for 12 to 48 hours before it begins to disintegrate and lose its fertilising capability. The most fertile days of your cycle are the two days following the day of release of the egg. The BabyWonderland Ovulation Calendar can help you calculate accurately your most fertile days every month by locating the day of egg release.

When do I ovulate?

Ovulation as a rule occurs 14 days from the first day of your menstrual cycle. Your menstrual cycle starts on the first day of your menstruation (first day of bleeding). The time of ovulation within the menstrual cycle is determined by the luteal phase, which is 12 to 16 days long. Your Ovulation Calendar will calculate the time of ovulation within your cycle by deducting the length of your luteal phase from the total length of your cycle. For example, if your cycle is 28 days long and your luteal phase is 12 days long, the ovulation will occur on day 16 of your cycle (28-12=16). However, factors such as stress, diet or illness can influence the time of ovulation, that’s why it’s recommended to keep the luteal phase length at an average of 14 days every month.

How does ovulation make me fertile?

Your fertile period starts about 4-5 days before ovulation, due to the capacity of the sperm to survive up to five days, and ends about 24-48 hours after the ovulation. Sperm has a life span of about five days, while the egg has a life span of maximum 2 days. You are most fertile on the day of ovulation and the day before ovulation.

What exactly happens during ovulation?

The Luteinizing Hormone (LH) is the hormone that triggers the ovulation process. One to two days before ovulation, the levels of this hormone increase considerably ('LH surge'), causing the egg to be released from the ovary. The egg travels down the fallopian tube towards the uterus to be fertilised and develop into an embryo. If fertilisation does not occur within 24 to 48 hours after its release, the egg disintegrates and is expelled with a uterus layer at the start of your next period, usually 12-16 days later (known as the luteal phase). If fertilisation occurs, the egg implants itself in the lining of the uterus resulting in a pregnancy.

How do I calculate my fertile days using the BabyWonderland Ovulation Calendar?

The BabyWonderland Ovulation Calendar calculates your fertile days based on the menstrual cycle data you enter. Enter the first day of your last period, the length of your menstrual cycle, and the length of your luteal phase if you know it. This usually is 12-16 days. Based on these data, our Ovulation Calendar generates your personal daily fertility chart showing the fertile days in green and the menstruation days in blue.

How can I determine the sex of my baby by using the Ovulation Calendar?

The sex of the baby is determined by the chromosomes brought in by the sperm. There are two types of chromosomes, X and Y. An XX combination will result in a baby girl. An XY combination will result in a baby boy. Sperm cells carrying X chromosomes are bigger and slower, but live longer. The Y chromosomes are smaller and faster, but die younger. The time of fertilisation sometimes determines the gender of the baby. So, if you have intercourse 3-4 days before ovulation and avoid intercourse starting with the day before ovulation, you have better chances of conceiving a girl because the Y-type sperm cells will die off, while the stronger and slower X-type cells will still be around ready to fertilise the egg. On the opposite, if you’re hoping for a boy, avoid having intercourse prior to ovulation and start the sexual activity on the day before ovulation, the day of ovulation and the day after. Our Ovulation Calendar will display female and male gender symbols on their respective days, but they can only be used as a guide.

Any natural signs of ovulation?

There are several signs of ovulation. The most accurate one is a slight increase in temperature (0.4-1.0 degrees Farenheit). The increase in temperature during ovulation peaks is your body's way of getting ready to keep the egg warm ready to be fertilised. Other signs are slight lower abdominal pains, changes in the cervical mucous (clear, slippery and stretchy, similar to raw egg white just before ovulation. This is nature’s way of ensuring a smooth journey for the sperms towards the egg). Our Basal Body Temperature Chart can help you locate ovulation based on your body temperature. Combined with the Ovulation Calendar, our Chart gives a precise and very useful monitoring of your monthly cycle.

Can I avoid pregnancy by using the Ovulation Calendar?

Yes, the BabyWonderland Ovulation Calendar can help you avoid pregnancy by calculating your fertile days and the days to avoid having sexual intercourse in order to avoid pregnancy.
