The ovulation calculator is used to calculate a woman’s fertile days. 
Ovulation is a phase of the menstrual cyclein which one of the ovary releases an ovum.
Usually occurs in about half the cycle, although the exact day can vary.
During each menstrual cycle, several ovarian follicles begin to mature and develop with the influence of pituitary hormones.
Usually only one follicle develops fully. Subsequently, the other follicles move away while the developed and dominant produces and releases an egg that can be fertilized.

Ovulation usually occurs between days 13 and 15 of the cycle, but in some cases can be anticipated.
This occurs in women with a short cycle.
The paradox of this situation is that you can get pregnant with the sexual relationship even if you have a menstruation.
The sperm remain alive inside the uterus for up to 6 days.
If a woman ovulates on day 10 but has unprotected intercourse on day 4/5 during menstruation, conception can occur on day 10 with the sperm remaining in the fallopian tubes.

Ovulation after an abortion
After a miscarriage , the woman has successive ovulation after 2-4 weeks.

 

How do you know if ovulation is occurring?

During each menstrual cycle, healthy couples in their twenties and thirties who are not using contraceptive methods have a 20% chance of getting pregnant.
This is a surprisingly high percentage considering that you can only conceive in the period of ovulation, a short period of time that usually lasts for 12-24 hours per month during which the egg is ready for fertilization.
We must consider that the spermatozoon is able to live and fertilize for three to six days from wherever it is.
The egg out of your living environment can not live long.
This means that even if you have sex a few days before ovulation, you can still have a lot of sperm in the female genital tract that can fertilize the ovum when it is released.
If there is aDelay of the cycle of a few days is best to take the pregnancy test .
Important: Only one sperm is enough to make a baby.
Of course, having intercourse on the day of ovulation would be ideal. After ovulation, the fertile period ends until the next cycle.
The following ways to understand if you are ovulating are not mathematical certainties, but often can identify the time of ovulation.

 

1. Calculation of calendar days

Ovulation often occurs in the middle of the normal menstrual cycle – the average cycle lasts for 28 days, from the first day of one cycle to the first day of the next.
A normal cycle can last 23-35 days, it can also vary a little from month to month.
Keeping a menstrual calendar for a few months helps you understand what normal cycles are for a woman.
The Ovulation Prediction Kit can help you find out the date and can be found at pharmacies.
If your periods are irregular , you need to be alert for other signs of ovulation.

 

2. Listen to the signs of your body

The 20% of women receive a reminder of the body when ovulation occurs.

You may feel a twinge of pain or a series of pains in the lower abdominal area. It is usually located only on one side, where ovulation occurs.
Central pain, this monthly reminder of fertility is thought to be the result of maturation or the release of an ovum from an ovary.
Pay attention because this symptom is likely to be felt during ovulation.

 

3. Plot the temperature on a chart

Se fala da temperatura corporal basal (TCB).
Use um termômetro especial (sim, você adivinhou, um termômetro basal do corpo).
A leitura da TCB deve ser feito como a primeira coisa da manhã, depois de pelo menos três a cinco horas de sono e antes de levantar da cama, falar ou até mesmo sentar-se.
A TCB muda durante todo o ciclo em correspondência com as flutuações nos níveis hormonais. A temperatura é inferior durante a primeira metade do ciclo que é dominada por estrogénio. Durante a segunda metade do ciclo há um aumento do hormônio progesterona (uma vez ocorrida a ovulação).
A progesterona aumenta a temperatura do corpo porque é preciso preparar o útero para a fecundação do ovúlo.

This means that in the first half of the month, the temperature is lower than in the second half of the month, after ovulation. Confused? Here is a summary: The TCB reaches its lowest point during ovulation and then gets up immediately and quickly (about half a degree) when ovulation occurs.
Try to remember the progress of the basal temperature for a month does not allow to predict the day of ovulation, but to give a test of ovulation after having occurred.
TCB charts monitored for a few months help you create a model for cycles, allowing you to predict ovulation day in advance for future months.
This way, we know when we can try to get pregnant.

 

4. Knowing the cervix

Ovulation is not a completely hidden process. When a woman’s body detects hormonal changes that indicate whether an ovule is being released by the ovaries, it prepares for the arrival of the spermazoid to create the conditions for fertilization. A detectable sign of impending ovulation is the position of the cervix itself.
The cervix is ​​a neck-like structure that lies between the vagina and the uterus and is dilated during birth to allow the baby’s head to pass.
During the beginning of a cycle, the cervix is ​​low, hard and closed.
However, as the ovulation approaches, it rises, softens slightly and opens to let the sperm get through to fertilize the egg.
Some women can easily feel these changes while others have more difficulty.
You can control your cervix every day using one or two fingers and keep a graph of the differences between day and night.

5. Another symptom of ovulation is the change in cervical mucus

The purpose of the mucus is to bring the sperm to the egg in the uterus.
When you approach ovulation, the cervical mucus changes in quantity and consistency.
When you are not ovulating, the cervical mucus may appear sticky or creamy or may be completely absent. When you approach ovulation the cervical mucus becomes more abundant, assumes a light color and a similar texture to a clear of raw egg.
When the cycle ends the uterus becomes dry.

Writing the position of the cervix, the basal temperature, and the type of cervical mucus in a single chart, can be an extremely useful tool to guess the day when ovulation is most likely.

 

6. Increased sexual desire.

It happens that nature knows what it is doing. Research has shown that women experience an increase in sexual desire when they are most fertile.
This occurs two days before ovulation, which is the right time to have sex if you want to get pregnant.

 

7. Breast pain is another symptom of ovulation.

Some women experience discomfort in their breasts before or after ovulation.
This is related to a hormone that runs in the blood and is used to prepare the woman for pregnancy. Several women have verified that the ultimate confirmation of ovulation is pain in the breasts .

 

8. Buy an ovulation forecast kit.

Do not you have to mess with the mucus?
It is not necessary today. The ovulation prediction kit is able to identify the date of ovulation 12-24 hours in advance by looking at the levels of luteinizing hormone or LH which is the last of the hormones that has a peak before ovulation actually occurs.
All you need to do is urinate in an absorbent cap and wait until the indicator reveals if you should ovulate.

How does the Ovulation Prediction Kit work? 
Ovulation prediction kits work as follows: they use urinalysis or saliva to detect the presence of certain hormones, which in turn indicate when ovulation is imminent.
A small amount of LH is always present in the blood and urine, but in the days before ovulation the amount increases from 100% to 500%.
The most fertile period of the cycle is 12 to 36 hours after the onset of LH.
This is the time when there are more possibilities to conceive.

How to use the Ovulation Prediction Kit? 
Depending on the brand of kit that looks at the urine, you can collect the urine in a cup or put an absorbent cap under the urine stream.
The colored bands appear on the card for the test or in the cap to indicate if you have reached the peak of LH.
The digital kit uses symbols, such as a smiling face to indicate which are the most fertile days.
The instructions may vary slightly depending on the kit you are using, but generally you should try to collect the urine between 10 and 20.
The best time is between 14 and 14.30.
Do not test the urine when you wake up, because you may miss the first day of the LH peak. Try to reduce the amount of fluids you take for about two hours before taking the test.
Too much fluid dilutes the urine and could make it harder to detect the peak.
Read the results within 5 minutes to get the most reliable results. A positive result does not disappear, but some negative results may show a poor range in the second color. After reading the result you have to throw away the absorbent cap.

 

Symptoms of pregnancy

The symptoms of pregnancy can vary as well as the menstrual pain are different for each woman.
