If you are trying to get pregnant, tracking your menstrual cycle can be very helpful.
A woman’s cycle typically last between 28 and 32 days. Note your periods on a calendar,
so that you can determine your average cycle. Our ovulation calendar will give you the date you are likely to ovulates.
Using this date the calculator will also provide you with the days that having sex will likely lead to a pregnancy.
Mark these days on your calendar!
Using the calendar, enter the date of your last period. Then enter the average length of your cycle.
The calendar will provide you with your most fertile days of the month. These are key baby-making days!
What is ovulation?
Ovulation is one phase of a woman’s menstrual cycle. During this phase, the ovary releases an egg.
The egg the makes its way to the fallopian tube and is ready for fertilization.
This means that a sperm cell can now fertilize the egg.
The egg will then move to the uterus and become a fetus.
Ovulation is a result of the release of hormones that results from a woman’s menstrual cycle.
Immediately prior to ovulation estrogen levels in the body rise to a peak level.
Using cues from the body, such as the increase in estrogen, signals are sent to the anterior lobe and pituitary gland
of the brain to secrete luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
This release of LH and FSH triggers ovulation.
Ovulation typically occurs between 10 to 18 days after menstruation.
So, around two weeks after a woman’s period, an egg is released and ready for fertilization.
It is important to note that the egg is only available to be fertilized between 12 and 24 hours after ovulation.
This gives the sperm a short amount of time to fertilize the egg.
An ovulation calculator can help you find a range of days during which you are fertile.
What are the phases of ovulation?
How can ovulation be detected?
There are many signs that a woman is ovulating. For example, during ovulation the cervical mucus thickens and increases
in volume.This is a result of increased estrogen levels in the woman’s body which accompanies the release of
the egg from the ovary. Ovulatory mucus is often described as thin and stretchy, like egg whites.
Ovulation can also be detected through the use of basal body temperature charting.
During ovulation a woman may notice an increase in body temperature by 4 to 1 degree.
This spike in temperature is due to the release of progesterone during the release of the egg from the ovary.
A woman is fertile during the two to three days leading up to the highest basal body temperature.
Three days before the temperature achieves its maximum.
Some women are able to sense when they ovulated, often by the presence of slight abdominal pain.
This pain is often described a mild ache or pang of pain.
This sensation is called Mittelschmerz (translated from german to mean “middle pain” and lasts from a few minutes
to a few re hours. Some women also experience a heightened sense of sexual desire during ovulation.
Finally, a woman may use an ovulation predictor kit, available at drug stores, to predict when ovulation is occurring.
This test detects the presence and increase in luteinizing hormone in the urine leading up to ovulation.
Often these kits provide a woman with a window of fertility, during which sex may lead to a pregnancy.
