How many days do you start ovulating after your period

When planning a baby, a couple needs to make sure that they are having regular intercourse and that it is at the correct time in a woman's menstrual cycle. Awareness of your fertility window increases your chances of conception.

The so called fertility window is the days in the menstrual cycle when conception is possible. This is from the day the egg is released (ovulation) and the five days prior.

The reason for this is that sperm can survive for up to five days and the egg for only 12-24 hours.  We recommend tracking your cycles and aiming for intercourse at least every second day during this time.

If you have irregular cycles, we recommend you aim for intercourse every second to third day.

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 (none of which are proven or endorsed by Fertility PLUS).

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.

Ovulation

There are bodily signs that change over the month that can help you to identify if you have ovulated.

Signs of ovulation

• Change in cervical mucus: Just before ovulation your cervical mucus changes to become clear and slippery, this is to allow the sperm to pass through the cervix. After ovulation the mucus becomes thicker and changes to a white/yellow colour, and hinders sperm transport.
• Changes in bodily hormones: Measuring a woman's luteinising hormone (LH) can help indicate ovulation, as the LH increases one to two days prior to ovulation. LH can be measured in the urine and is the basis of commercial ovulation kits. These are generally used for five to six days prior to your expected ovulation day. Commercial ovulation kits should be used with caution as there is limited evidence of the effectiveness in improving fertility outcomes.
• Changes in body temperature: Measuring your 'basal temperature' has been used to help identify if ovulation has occurred. Fertility PLUS does not recommend this technique as it is often inaccurate and can increase your stress levels. It is a retrospective test, so once your temperature has increased, you have already ovulated, potentially missing your fertility opportunity.

Your fertility window is the time during your menstrual cycle when you’re most likely to get pregnant. For most people, it’s the five days leading up to ovulation, the day of ovulation and the day after ovulation. Calculating your monthly fertility window can help you target the optimal time to have sex if you’re trying to conceive. However, natural family planning is a less reliable form of contraception and does not protect against sexually transmitted infections.

Understanding Your Menstrual Cycle

If you’re trying to get pregnant and want to track ovulation, you need to understand your menstrual cycle. Your menstrual cycle is your body’s way of preparing for pregnancy. It begins on the first day of your period and starts over when your next period begins. A typical menstrual cycle is 28 days, but cycles ranging from 21 to 35 days are considered normal.

Lots of changes happen in your body during the cycle, including hormone fluctuations. About halfway through, one of your ovaries releases a mature egg. The egg goes to one of your fallopian tubes, where it waits to be fertilized by sperm. The lining of your uterus gets thicker, too. This prepares the uterus for implantation of the fertilized egg.

If you don’t get pregnant, it could mean that the egg didn’t fertilize, or that the embryo (fertilized egg) didn’t implant into the uterus. In those cases, the uterine lining sheds and you get your period.

When am I ovulating?

Knowing when you’re ovulating is key to tracking your fertility window and determining the best time to get pregnant. There are a few different fertility awareness methods, also called rhythm methods. It’s best to use all three methods if you’re doing natural family planning.

Calendar method

Use the calendar method to track the length of your menstrual cycle. Each month, mark the first day of your period on a calendar or in a period-tracking app. The number of days between the first day of consecutive periods is the length of your menstrual cycle. You should do this for at least six months to get good data.

You ovulate about 12 to 14 days before the start of a new menstrual cycle. Your fertile window is the five days leading up to ovulation, plus the day of ovulation and the day after ovulation — so about seven days in total.

It’s important to note that if you have irregular periods and the length of your menstrual cycle varies from month to month, the calendar method won’t be accurate for you.

Cervical mucus method

Hormone fluctuations during your menstrual cycle change the amount and consistency of your vaginal mucus. You need to feel and look at your vaginal mucus each day and record the results on a chart. You’re likely ovulating (and most fertile) when the mucus is heavy, wet and slippery. It will have the consistency of raw egg whites.

You should chart your vaginal mucus for at least one menstrual cycle. It may be difficult at first to know what to look for, so talk to your provider if you want to try this method. He or she can explain how to chart and describe the mucus each day.

Ovulation predictor kits

Ovulation predictor kits are an at-home tool to help predict your ovulation. These tests may be helpful if you have regular periods, but still aren’t quite sure if you are seeing natural signs of ovulation (cervical mucus or a rise in basal body temperature). Ovulation predictor kits test your urine for levels of luteinizing hormone. When the ovulation predictor test becomes positive, ovulation will typically occur within 24 hours, indicating that you’re fertile and should have sex. These kits might not be reliable if you have irregular periods due to polycystic ovarian syndrome.

Basal body temperature method

Also called the temperature method, you take your temperature each morning as soon as you wake up (before you get out of bed). You use a basal body thermometer, which may go in your mouth or your rectum. A basal thermometer is more sensitive than a regular thermometer. It measures body temperature to a tenth of a degree.

A woman’s basal body temperature rises slightly during ovulation (increases by 0.5 degrees Fahrenheit). If you track your temperatures leading up to ovulation, you should see a sustained rise in your basal body temperature after ovulation.

To help you plan, write your body temperature down each day on a tracking sheet. You should track your temperature for at least three months before using this method for family planning.

However, it’s important to note that the basal body temperature method is not good at predicting your ovulation when trying to conceive. Once you identify the rise in your temperature, you’ve already ovulated. However, this method is a good tool to monitor your pattern of ovulation.

Should I have sex before, during or after ovulation?

For the best chances of pregnancy, you should have sex every day or every other day during the:

• Five days leading up to ovulation
• Day of ovulation
• Day after ovulation 

There’s a lot of information (and misinformation) about methods for having sex that could increase your chances of getting pregnant. There’s no specific sex position that increases your odds of conceiving. Some lubricants may negatively affect sperm and prevent them from reaching the egg. Talk to your health care provider about which lubricants to avoid.

What if I have irregular periods?

If you have irregular periods, meaning that your periods are outside of the 21–35-day window or if your cycle intervals vary by more than seven days each month (30-day interval one month, 23 days the next month), you should speak with your Gyn/OB or a fertility specialist. This irregularity may be due to a hormone imbalance and could make it more challenging to get pregnant using natural family planning methods.

How else can I prepare for pregnancy?

In addition to tracking your ovulation to determine your fertile window, it’s important to schedule preconception counseling with your doctor. There are a variety of screenings and lifestyle modifications that can help increase your chances of a successful planned pregnancy.

If you’re under 35 and have been trying to conceive for more than a year, or if you’re over 35 and have been trying for six months, it may be time to talk to your doctor about why you can’t get pregnant.
