How Do I Use The Calendar Method
Before you can use the calendar method as birth control, you need to keep track of the length of your menstrual cycles for at least 6 periods. You can do this with a regular calendar or our period tracking app.
Heres how you do it: Mark the first day of your period . Then mark the first day of your next period. Count the total number of days between each cycle .
You must chart at least 6 cycles, but charting a few more months is even better. Heres an example:

If all of your cycles are shorter than 27 days, the calendar method wont be accurate for you.
When To See A Doctor
Women who track their fertile window with the aim of getting pregnant should see their doctor for preconception planning.
As well as identifying barriers to conceiving, a doctor can advise on the use of folic acid or prenatal supplements to encourage a healthy pregnancy.
Most couples who engage in frequent, unprotected sex will conceive within 12 months.
Women under 35 years of age should see their doctor if they do not conceive after a year of trying. Those over 35 years of age should seek medical advice after 6 months of trying to conceive.
Anyone who has irregular cycles or does not appear to ovulate should also speak to their doctor. There may be an underlying medical cause that is preventing ovulation and conception.
Ovulation predictor kits and fertility monitors are available for purchase online.
Understanding Your Menstrual Cycle
Your menstrual cycle begins on the first day of your period and continues up to the first day of your next period.
Youre most fertile at the time of ovulation , which usually occurs 12 to 14 days before your next period starts. This is the time of the month when youre most likely to get pregnant.
Its unlikely that youll get pregnant just after your period, although it can happen. Its important to remember that sperm can sometimes survive in the body for up to 7 days after you have sex.
This means it may be possible to get pregnant soon after your period finishes if you ovulate early, especially if you have a naturally short menstrual cycle.
You should always use contraception when you have sex if you dont want to become pregnant.

Determining The Best Time To Have Sex To Conceive
Unfortunately, theres no completely accurate method to detect that you are about to ovulate. Its possible for an ovulation predictor kit, body temperature charts, and cervical mucus patterns to all indicate a slightly different ovulation day.
In a study of people with regular, 28-day cycles, ovulation occurred most commonly on day 15 after the start of the last menstrual period , followed by day 16 LMP and day 14 LMP . Researchers found a 10-day spread of observed ovulation days even among a group of people with clockwork cycles, and a similar variation for people whose cycles were a little longer or shorter.
Another group of researchers set out to pinpoint the most commonly fertile day in the menstrual cycle across the general populationincluding those with irregular cyclesusing menstrual period surveys and ultrasound measurements rather than ovulation signs. They found a sharp rise in the probability a person will conceive beginning at day 7 LMP, reaching a maximum probability of conception of 13% at day 15 LMP. By day 25 LMP, the statistical probability of conception is zero, according to the data.

Is There Any Correlation Between Age And Fertility
Technically, any woman who is ovulating and sexually active is capable of becoming pregnant. But when it comes to age, the answer to “when is a woman most fertile?” is when shes younger.
As your ovaries and eggs age, it becomes harder to successfully conceive and carry a pregnancy to term. Hormonal fluctuations in perimenopause create irregular cycles that are sometimes anovulatory . This makes it more difficult to conceive.

However, its still possible to get pregnant after the age of 35. Make an appointment with your doctor to test your hormone levels and zero in on any possible barriers to conception after six months of trying without success.

Fertility During Your Period
A menstrual cycle is a cycle that begins inside a woman’s reproductive system on the first day of her period. This is not to be mistaken for the actual ‘period’, which is simply the act of bleeding.
Cycles can be regular or irregular and can last anywhere between 21 and 35 days. They are not always consistent and even for the same woman, one cycle can be very different from the next. A regular menstrual cycle only fluctuates between 21 to 35 days while an irregular menstrual cycle can be inconsistent and unpredictable, this usually lasts less than 21 days or more than 35 days. Knowing your menstrual cycle, period, and when you ovulate can help you pick the right time to have unprotected sex to get pregnant.
If you are a woman who has been going through cycles for quite some time now, you will more or less have an idea of what you might find in this article. However, if you are new to all this, perhaps you are a person trying to conceive or are wanting to learn more about contraception, here are some explanations of terms that you need to know before moving forward.
Ovulation: This is when a mature egg cell is released from the ovary into the fallopian tube where it gets a chance to be fertilized by a sperm cell. The egg will stay in the tube for about 24 hours, which is the best time to have sexual intercourse and increase the chances of pregnancy. Whilst ovulation happens as part of a cycle, some women can ovulate early from time to time.
Getting To Know Your Cycle
How To Track Your Cycle
Working out your fertility window can be helped by tracking your menstrual cycle. You can simply mark your periods on a calendar or try some of the many apps available online .
The average menstrual cycle is 28-35 days. Ovulation usually occurs 14 days prior to your period starting. We recommend you track two to three cycles and work out the average length of your cycle. From this you can work out the average time you are likely to ovulate.
- If your cycle is 28 days, ovulation should occur on day 14. Therefore aim to have regular intercourse from 10 days after your period has started.
- If your period is 35 days, then ovulation should occur at 21 days and intercourse should be from 17 days after your period started.

When Do Periods Stop
Your periods will continue until you reach the menopause, which usually happens when you are in your late 40s to mid-50s. In the UK the average age of menopause is 51.
Your periods may start to become less frequent over a few months or years before stopping altogether. In some cases they can stop suddenly.
Can You Get Pregnant A Week After Your Period
Yes, you can get pregnant a week after your period. There lies a possibility to conceive a week after your period if you have sex without contraception. It is more likely for women with a shorter menstrual cycle since their fertile window gets activated earlier.
Take home message: Always use effective contraceptive methods while having intercourse unless you are planning pregnancy, as none of the days of the month in menstrual cycles can be claimed as 100% safe days.

What Is The Best Way To Determine When Youre Most Fertile
Being aware of your menstrual cycle and the changes in your body that happen during this time can help you know when you are most likely to get pregnant.
The average menstrual cycle lasts 28 days. But normal cycles can vary from 21 to 35 days. The amount of time before ovulation occurs is different in every woman and even can be different from month to month in the same woman, varying from 13 to 20 days long. Learning about this part of the cycle is important because it is when ovulation and pregnancy can occur. After ovulation, every woman will have a period within 14 to 16 days.
Knowing when you’re most fertile will help you plan or prevent pregnancy. There are three ways you can keep track of your fertile times:
How Long Should A Normal Menstrual Cycle Last
An average menstrual cycle lasts 28 days, defined from the first day of menstrual bleeding to the first day of bleeding of the next period. However, irregular periods are very common. An irregular period is defined as a cycle that varies by more than seven to nine days.
There are several reasons why women may have abnormal periods, which can include fibroids, ovarian cysts, polyps, and even something as common as stress.
If youve constantly had an irregular period, please contact us for an appointment to determine the underlying cause and initiate treatment, said Dr. Martinelli.

Why Should You Calculate Your Safe Period
Calculating your safe period is advantageous because it will help you understand what days it is favourable to have sex without protection and with no pregnancy scares. Knowing how to calculate your safe period is essential if you do not wish to have a child right away. However, more importantly, safe period calculation is a great method of birth control because it does not involve ingesting hormonal birth control pills, using an IUD, or hormone injections which can have different effects on different women, ranging from extreme mood swings to weight gain and other problems that hamper ones well-being.
Is It Safe To Have Sex After Periods
Whether you are trying to avoid getting pregnant or trying to conceive, you should be tracking your menstrual cycle. This means you should be monitoring the period between the first time you get your period to the next. The average woman begins to ovulate about 14 days after her menstrual cycle has ended. However, the most fertile period of the female is about 3-4 days before and after her ovulation period. Hence, it is not safe to have sex during these 3-4 days if you do not want to get pregnant and advisable to have sex during this period if you wish to do so.

What Is The Cervical Mucus Method Of Determining Fertility
The cervical mucus method involves being aware of the changes in your cervical mucus throughout the month. The hormones that control the menstrual cycle also change the kind and amount of mucus you have before and during ovulation.
Right after your period, there are usually a few days when there is no mucus present or dry days. As the egg starts to mature, mucus increases in the vagina, appears at the vaginal opening, and is white or yellow and cloudy and sticky. The greatest amount of mucus appears just before ovulation. During these wet days it becomes clear and slippery, like raw egg whites. Sometimes it can be stretched apart.
This is when you are most fertile. About four days after the wet days begin the mucus changes again. There will be much less and it becomes sticky and cloudy. You might have a few more dry days before your period returns. Describe changes in your mucus on a calendar. Label the days, Sticky,Dry, or Wet. You are most fertile at the first sign of wetness after your period or a day or two before wetness begins.
The cervical mucus method is less reliable for some women. Women who are breastfeeding, taking hormonal birth control , using feminine hygiene products, have vaginitis or sexually transmitted infections , or have had surgery on the cervix should not rely on this method.
How Many Days After Your Period Are You The Most Fertile
Ovulation happens about 14 days before your period starts. If your average menstrual cycle is 28 days, you ovulate around day 14, and your most fertile days are days 12, 13 and 14. If your average menstrual cycle is 35 days ovulation happens around day 21 and your most fertile days are days 19,20 and 21.
