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.
See other ways to pinpoint your fertile days and increase your chances of becoming pregnant. Find out how to use an ovulation predictor kit, chart your basal body temperature, and pay attention to changes in cervical mucus.
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.
Best menstrual cycle tracker. Plus I upgraded to premium and the features are great. More like an all around health app. Nutrition plans, sleep courses, daily health care advice from doctors for women.
Apple Watch Series 8 or later, and all Apple Watch Ultra models, use wrist temperature data to detect the biphasic shift, which is an increase in temperature that often occurs after ovulation. Advanced algorithms use wrist temperature data and logged cycle data to estimate the day ovulation likely occurred.
The Premom app, which is free to download and used by hundreds of thousands of people, helps users track ovulation, periods, and other health information, and also sells ovulation test kits. The app encourages users to provide information about their menstrual cycles, fertility, and pregnancy as well as to import their data from other apps such as Apple Health.
The Ovulation Calculator estimates the most probable ovulation/fertile window as well as other related dates. The estimations are based on a woman's last period date. This calculator should not be used as a form of birth control.
Ovulation in humans is the process by which ovarian follicles rupture and release one or more mature eggs from the ovaries. On average, ovulation occurs within the 4 days before or after the midpoint of a woman's menstrual cycle (14 days before the start of a woman's next menstrual period).
Day 10-18 of the menstrual cycle (on average) is the most fertile phase of the menstrual cycle. This is important when trying to conceive because fertilization of the egg can only occur for 12-24 hours after release during part of the luteal phase, when a mature egg travels through the fallopian tubes towards the uterus. Since sperm can survive inside a woman's body for up to five days, regular sex five days before and on the day of ovulation can improve the likelihood of conception. If fertilized, the egg will implant in the uterus 6-12 days later. Otherwise, menstruation occurs, and blood and mucosal tissue from the inner lining of the uterus is expelled.
This ovulation calculator uses the method of tracking menstrual cycles in order to predict when ovulation occurs. Since day 10-18 of the menstrual cycle is typically the most fertile phase of the menstrual cycle, women with regular cycles can fairly easily determine when they are ovulating and most likely to conceive. Menstrual cycles vary between women however, and a person without a 28-day menstrual cycle may need to track their menstrual cycle to more accurately determine when ovulation might occur.
The first day of the menstrual cycle is the day that bleeding starts, and it ends the day that bleeding starts again. It can be helpful to maintain a menstrual calendar to determine how regular your periods are. If they are irregular, other methods may be more accurate for estimating when ovulation will occur.
Basal body temperature (BBT) is measured using a special thermometer. This is your temperature when you first wake up in the morning. BBT is generally at the lowest level right before ovulation occurs. It starts rising by about a degree a day during ovulation. Tracking BBT over a few months can help you determine when you are ovulating and most likely to be able to conceive. However, there are other factors involved that can affect your BBT, such as having a cold or infection. In these cases, measuring BBT would likely not be a good indicator of ovulation.
It is also possible to use an over-the-counter ovulation test that tests for a surge in some specific hormones that precede ovulation by 24-48 hours. While these tests are 99% accurate in detecting the specific hormones, they cannot guarantee when exactly ovulation will occur within the two-day period. These tests typically measure the level of luteinizing hormone (LH), which, when released in high quantities (and under other conditions), triggers ovulation.
There are also ovulation predictor kits that can test changes in the estrogen level in saliva or salts in the sweat, which change during the month and can be related to the menstrual cycle. These changes generally occur earlier than the hormonal changes (LH increase), and can therefore predict ovulation earlier. Unlike LH tests, this does require more preparation in terms of tracking the levels of these markers to determine a baseline level.

We hope this tracker can be a helpful tool on your journey to conception! Sometimes the fertile window can feel elusive, but keeping tabs on your fertile window should help you get a grip on your unique cycle. Learn more about Ovulation Tests here.
Introduction: Using an online survey, the aim of this study was to ask women about their real-life experiences of using period tracker apps, their attitudes towards using their app, the information the app provided regarding ovulation and how the accuracy of the app in predicting period start dates affects their feelings and behaviours if their period comes earlier or later than predicted.
Methods: This mixed-methods observational study was conducted by an online survey of 50 multiple-choice and open-ended questions. The survey was generated with Qualtrics XM and promoted via social media. It was open to any person who had used a period tracker.
Conclusion: Period trackers need to be clearer on their intended use and reliability, especially for period due date and ovulation. Qualitative analysis shows the impact of inaccurate predictions on aspects of the users' health. This study calls for period tracker app companies to update their apps to provide transparency to their users about their intended use and capabilities.
Not allowing third-party tracking: Third-party trackers allow companies other than the app-maker to collect data about your activity for purposes such as optimizing app performance or targeting you with ads. Refraining from using any of these trackers is a critical privacy protection. When your data reaches a third-party company, it can be traded, shared, or sold repeatedly, with no realistic way for you to ever find out where it has gone or ask for it to be deleted.
The reasons why respondents downloaded and started using a period trackerapp. They were able to tick all the answers that applied. Of 330 women,the major reason was to understand their symptoms, changes and concernsabout their menstrual cycle.
Further to this, respondents were aware that anxiety can delay periods further.They described how the nerves and stress created by a late period, as classifiedby their period tracker, can cause their period to start even later.
