Period and Ovulation Tracker overview
Version 1.1 released at 01/27/2023
Menstrual periods are different from woman to woman and month to month. Use out Period and Ovulation Tracker to see when you may be ovulating to help find your most fertile days.
How do I use the ovulation tracker?
To find out your next fertile dates, you just need to select the date of the first day of your last (or any) period, adjust your average cycle length. Your cycle length is the number of days between your periods, counting the first day of your period until the day before your next period starts. You will then receive your upcoming fertile dates. This is just a guide to help you understand when you may be most fertile.
What if my periods are irregular?
You may have irregular periods if you can’t count your cycle and work out within a day or 2 when your period is due. This can make it harder to identify your ovulation date. But there are other ways of working out when you may be ovulating, such as changes in vaginal mucus, ovulation testing kits or measuring your temperature.
When is the best time to conceive?
To increase your chances of getting pregnant, you need to get your fertile eggs and sperm together as often as possible. You’re the most fertile on the few days each cycle around ovulation, which is when an egg is released.
During an average menstrual cycle, there are 6 days when sex can result in pregnancy. This is regularly called the “fertile window” and includes the 5 days before ovulation and the day of ovulation itself.
Some people get pregnant very quickly, but for some people it can take a little longer.
How does the menstrual cycle work?
- Your cycle starts on the first day of your period and continues up to the first day of your next period.
- This is 28 days on average, but it’s normal to have a cycle that lasts between 20 and 45 days.
- At the same time, eggs begin to mature in the ovary.
- The lining of the womb thickens ready for fertilization.
- During ovulation, your cervical mucus becomes thinner and clearer to help the sperm reach the released egg.
- About 12 to 16 days before the start of your next period, an egg is released from your ovaries (ovulation).
- If sperm is present during ovulation, or some time during the next 24 hours, the egg may be fertilized.
- If the egg has not been fertilized, the egg is re-absorbed by the body, the hormone levels drop, and the womb lining is shed. This is the beginning of your next period.
Conception and sex
Regular sex (every 2 to 3 days) is all most people need to conceive. If you’re under 40 and have regular sex without using contraception, you have an 80% chance of getting pregnant within a year.
To boost your chances of conceiving, aim to have regular sex throughout your cycle, so you know that there should hopefully be good-quality sperm waiting for the time that the egg is released. Remember that if you’ve had sex in the 7 days before ovulation, it’s possible to get pregnant because sperm can live inside a woman’s body for up to 7 days and fertilize the egg when it’s released.
If you know when you ovulate each month, you can give yourself the best chance of getting pregnant by having sex in the days leading up to ovulation. Continue having sex during ovulation, as you can still get pregnant. After this time, your fertile time will be over for that cycle.
