Knowing the days you are most likely to be fertile can increase your chance of getting pregnant. The typical menstrual cycle is 28 days long, but each woman is different. There are about 6 days during each menstrual cycle when you can get pregnant. This is called your fertile window. Use the calculator to see which days you are most likely to be fertile.
This ovulation calculator provides an estimate of your fertile window and is not a guarantee of pregnancy or of birth control. The calculator and information on this website are not medical advice. Talk to your doctor or nurse to plan for pregnancy and find birth control that works for you.

Generally, you ovulate in the middle of your menstrual cycle. If you have an average 28-day cycle, you may ovulate around day 14. However, lengths of normal cycles can vary from 21 to 35 days. Some women ovulate around the same day each cycle, but for others the timing is hard to pinpoint. That's why it's helpful to look for ovulation symptoms if you're trying to get pregnant.
Ovulation can cause mild discomfort in the form of light cramps or twinges in the abdomen, or a one-sided backache. Ovulation cramping is known as mittelschmerz (German for \"middle pain\"). Some women don't have any ovulation cramping, though.
By tracking your ovulation cycle, you can know when is the best time for you to have sex with your partner if you want to have a baby. Ideally, if you have sex within your ovulation period, the chances of pregnancy are fairly high.
Our ovulation calculator and fertility calendar show you when you're most fertile, to help improve your chances of getting pregnant. Every woman's menstrual cycle is unique, so discovering your own fertile window will help you work out when you have the best chance of conceiving a baby.
Sperm can live in your body for a few days, so you may conceive if you have sex in the days leading up to ovulation. During the 24 hours after ovulation, the egg travels down the fallopian tube towards your womb; if the egg meets a sperm at this point, conception could also happen then.
Our calculator will work out when your cycle will end, and count back two weeks to estimate when you may ovulate. It will then create a personalised fertility calendar showing your full fertile window each month for the next six months.
If your cycles are irregular, you may have trouble pinpointing your day of ovulation based on this calendar alone. Find out about ovulation predictor kits (OPKs), or read more ways to predict ovulation using your basal body temperature, cervical mucus and more.
Once an egg has been released, it's ready to be fertilised. When you have sex, sperm can live inside your body, waiting for an egg to be released, for up to a week. So having sex in the days before ovulation, and on the day you ovulate, gives you the best chance of getting pregnant.
After ovulation, your egg travels down the fallopian tube towards your womb. It can stay alive for 12-24 hours after ovulation, so there's also a chance of getting pregnant the day after ovulation, too.
The main hormones involved in ovulation are luteinising hormone (LH) and follicle stimulating hormone (FSH). At the right point in your cycle, the brain produces these hormones, which prompt the ovaries to release an egg.
On an average 28-day cycle, ovulation most often happens 14 days after the first day of your period. The time between the first day of your period and ovulation is known as the follicular phase, while the time after ovulation is known as the luteal phase.
Our calculator will estimate the dates up to, and including the day of ovulation, which is when you're most fertile. But there are other signs and symptoms of ovulation that can give you a clue to your fertile window. These include:
Because this increase in temperature happens after ovulation, it won't help you conceive during this cycle. However, by tracking your temperature over time, you may learn when you can expect to ovulate next and use this to work out your next fertile window.
Around the time of ovulation, your cervical mucus may be clear and slippery, a bit like raw egg white. This is likely to happen during your most fertile days, so it's a good time to have sex if you want to conceive.
The most common type of ovulation test works a lot like a pregnancy test. It detects the level of luteinising hormone (LH) in your pee. LH is the hormone that triggers ovulation, so a positive result means you're likely to ovulate soon, making it the perfect time to have sex if you want to get pregnant.
There are lots of different apps available to help track your menstrual cycle and work out when ovulation is most likely. These rely on regularly tracking your periods, plus other symptoms such as your temperature and changes to your cervical mucus.

Implantation usually happens about 8-10 days after ovulation, though it can sometimes happen as early as 6 days after ovulation. However, even after implantation, it will take several more days for pregnancy hormones to build up enough to be detected by a pregnancy test.
For some women, ovulation can feel like a sharp and sudden pain or a dull cramping sensation, low down on one side of your tummy. Not everyone gets ovulation pain when their ovaries release an egg, but if you do, it may last for just a few minutes or up to two days, and may be accompanied by light bleeding or discharge.
Ovulation is a part of your monthly cycle. Your ovulation occurs during each menstrual cycle, this is once a month. During ovulation the mature follicle bursts, this releases the egg and makes its way to the fallopian tube. The egg can be fertilized up to 24 hours after ovulation. Is the egg not fertilized? Then it will dissolve and your period will slowly begin.
To get pregnant, it is helpful if you know what your most fertile days are. To find out, you need to know what your menstrual cycle is. An average menstrual cycle lasts 28 days, where day 1 is the first day of your period. At approximately half of that cycle (day 14) the ovulation takes place and you are fertile. Below you will find a handy schematic representation of your most fertile days.
Infertility affects a significant portion of couples seeking pregnancy, leading to stress and emotional strain. Ovulation calculators, widely used as a tool to predict fertile days, may play a role in the stress experienced by couples undergoing fertility treatments. The aim of this study was to evaluate the impact of ovulation calculators on the stress levels of couples seeking fertility.
Participants were recruited from the University of Miami Health System Clinics. Fifty couples consulting for infertility were asked to participate in the study and complete anonymous self-reported surveys. The surveys consisted of validated questions related to stress levels and the use of ovulation calculators. The completed surveys were collected and analyzed using descriptive statistics. The data collected included age, number of years trying to conceive, and answers to questions related to stress levels and the use of ovulation calculators. Responses from 50 couples who met the inclusion criteria were included in the final analysis.
