You have made the decision to get pregnant, and want to do everything possible to make this happen as quickly as possible? We offer you to use an online ovulation calculator to determine the most favorable days for conception. And in this article we will answer the most common questions associated with ovulation and conceiving a child.
What is ovulation calculator?
Also known as ovulation calendar, conception calculator, fertility calendar or calculator fertility, this tool takes into account your average length of cycle and luteal phase, to give you the most accurate window of fertility. This calculator not only gives you an estimate based on averages of other women, it allows you to substitute your own numbers to adjust the result to your personal cycle.
What is luteal phase?
Luteal phase the second half of the menstrual cycle, beginning with ovulation and ending with menstruation or a new pregnancy. During this period you have going on is a huge release three important hormones:
- Follicle-stimulating hormone: released into the bloodstream from the pituitary to stimulate the ovarian follicles that secrete estrogen and produce Mature egg (or two in case of twins).
- Luteinizing hormone is also released into the bloodstream from the pituitary gland in response to increased estrogen levels. This important hormone causes the follicle to release an egg for potential fertilization.
- Progesterone: as estrogen levels fall with ovulation, the progesterone level begins to rise, to make a thicker uterine lining for potential implantation of the egg. Progesterone levels will continue to rise, if you get pregnant.
The average luteal phase is 14 days (half of the average 28-day cycle), but may vary within the normal range of 12 to 16 days. You can track symptoms of ovulation for a more precise definition of the duration of the luteal phase or just use test for ovulation.
If your luteal phase lasts less than 10 days, consult your doctor, who will help you to increase the production of progesterone. Short luteal phase reduces the chances of a successful conception of a child.
How many days after menstruation and lasts for ovulation?
On average, ovulation starts about 14 days after the onset of menstruation. This indicator is based on a 28 day cycle and 14 day luteal phase. If your cycle is (or luteal phase) differ from the average, you should count back 14 days from the next predicted menstrual period.
For example, if your cycle lasts 30 days, ovulation may begin within 16 days after the start of menstruation. Similarly, if you have the average 28 day cycle, but your luteal phase is 16 days, the ovulation will start after 12 days after the start of your last menstrual period. The information may seem confusing, we recommend to use ovulation calculator. Just enter your information in this online calculator and let it determine your fertile period.
When fertility is at its peak?
Fertility is at its peak on the day of ovulation. As the lifespan of the sperm does not exceed 5 days and the egg is 24 hours, the window of fertility lasts for 6 days. Imagine it in the form of waves. Fertility starts to increase on the 10th day, then it reaches a maximum at the 14th day and falls during the day or two.
What is the window of fertility?
The fertility window is the time during a cycle, which is likely to result in conception. The window of fertility depends on your cycle length and luteal phase, so each woman is individual. Using the average cycle length (28 days) and luteal phase (14 days), we can calculate that the window of fertility falls to 10-16 days of your cycle.
How to calculate the days of greatest fertility?
To calculate your most fertile days, you should first calculate the average length of your cycle. Then you need to determine your luteal phase. Assuming that the average luteal phase is 14 days, the days of greatest fertility is 13-18 days before the expected menstruation. For a 28-day cycle would be days 10 through 16.
How to calculate your ovulation day?
Calculate ovulation day a little easier, because ovulation occurs only one day per month. If we assume that the luteal phase lasts 14 days, your day of ovulation will take place 14 days before next expected menses. When 28-dnevnom cycle the egg is released on the 14th day.
Swiss scientists have called the most accurate method for determining the period of ovulation in women is the urine test. For many couples who have difficulty conceiving a child, the knowledge that time is extremely important. Traditional calendar method is not able to give accurate result, it is only possible to understand the workings of the menstrual cycle. So, the calendar method is valid only for 25% of women, and urinalysis in 99% of cases.
The high accuracy of the calendar method is due to the fact that 46% of healthy women 18-40 years of age length of menstrual cycles can vary by 7 days or more, because the formula of the length of the menstrual cycle minus 14-15 days does not always work.
Can there be menstruation without ovulation?
Yes. Some researchers believe that up to 30% of the regular cycles are anovulatory (ovulation does not occur). It is possible that even in the absence of anovulation (which means that you have a regular cycle), it does occur.
Can you get pregnant not the window of fertility?
Yes you can get pregnant anytime of your cycle, even during menstruation. If you are aiming to get pregnant should focus on the more auspicious days, but it is good to remember that any intimate relationship could potentially lead to pregnancy, especially if your cycles are irregular.
