4 day period when do i ovulate

Timing is everything

If you’re trying to fall pregnant, the timing of when you and your partner have sex is critical. Our new online calculator will help you understand your Fertile Window - so you know the best time to have sex to give you the highest chance of conceiving.

When am I most fertile?

The most fertile time in your cycle are the days leading up to ovulation, before the egg is released from the ovary.  After ovulation the egg survives for just 24 hours, while sperm retain fertilising capability for two to three days in the fallopian tubes.   For this reason, we recommend that couples have sexual intercourse every two days throughout the females Fertile Window.  This means that sperm are ready and waiting for the egg when the female ovulates.  If you wait until after the female has ovulated before you have sex, you will most likely have missed the opportunity for conception that month.

When does conception take place?

Conception starts at the moment of fertilisation, when the sperm penetrates the outer shell of the egg, and an embryo is formed. Over the next four to six days the embryo moves down the fallopian tube to the uterus, where it implants in the uterus lining and hopefully continues to grow. To check if you are pregnant, you should wait two weeks after ovulation before undertaking a pregnancy test.

Calculate Your Fertile Window

To calculate your Fertile Window, you need to determine what day you ovulate.To do this, you need to know the length of your menstrual cycle (which tends to vary from 23 to 35 days). To calculate this – you should note how many days have passed from the first day of bleeding in your last period, to the first day of bleeding in your next.From this figure, subtract 14 days from the end of your current cycle to determine the day you ovulate.If you have irregular menstrual cycles, or your cycle length varies from month to month, it will be difficult to calculate your ovulation date. Ovulation urine tests may be useful, and you should consider seeking further advice from your GP or a Fertility Specialist.

How long should I try for, before seeking specialist advice?

Conception is a complicated sequence of events because all of the following need to be in place for it to occur:

• Regular egg production by the ovaries (ovulation)
• Healthy sperm, with the ability to move (motility) and the correct shape (morphology)
• Unblocked and healthy fallopian tubes and uterus

The number one factor affecting a couple’s chances of conceiving is the woman’s age. The number of healthy eggs a woman’s ovaries contain will dramatically decline with age; and especially for women over 35. Most people start to consider seeking professional advice after six months of trying to conceive naturally without success. This is even more important if you’re over 35.

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.
