How to Calculate Ovulation for Irregular Cycle

Even if your menstrual cycles are beyond the normal 28 day cycle, you can still calculate ovulation with an irregular menstrual period.

It is easy to tell when ovulation occurs, if you have a regular menstrual period. But many women have problems in finding out when their fertile period is, because of irregular cycles, and they may find it very difficult to get pregnant. Would you like to know how to calculate ovulation for an irregular menstrual period? It is possible and it is easier than you think. So, if you and your partner have no infertility problems, and you believe that you are just missing the ‘right days,’ you should start calculating. Here are the top 3 methods to do it.

Use a calendar

First of all, you should precisely know your cycle days. Record them for a long period of time, in order to get the best ovulation predictions. You may even find out that your cycle is in fact regular (for example, it lasts for 40 days instead of 28, or something similar), but longer or shorter than the average. If you know how long your cycle is, remember that you should have intercourse in the middle of the menstrual cycle, because it is then when ovulation should occur.

Extra tip: try having sex in the days before and after the probable ovulation too. This way, your chances to get pregnant will be higher.

Monitor the cervical mucus

Most of us know that the amount of cervical mucus changes in some points of the menstrual cycle, especially when ovulation occurs, so it is a great indicator in this regard. After menstruation, there is almost no cervical mucus and then it gets thicker and more abundant. In the ovulation days, there is more cervical mucus than usual and it looks like egg whites. This is the proper period when you should try to conceive.

Basal body temperature

The basal body temperature gets up to one degree higher when you ovulate, so it is also a great way to discover the fertile days. Note that you need a digital thermometer for accurate results. Take your temperature as soon as you wake up, even before you get out of bed, as once you start your everyday routine, the basal temperature may rise because of various external reasons (such as stress), and thus you will not be able to find out when your fertile period is.

Try these simple tips on how to calculate ovulation for irregular menstrual period and maybe you will soon be surprised by a positive pregnancy test.

    I do recommend that you try to purchase an Ovulation Predictor kit in order for you to track your ovulation date and fertile window dates. If you have a regular 28-day cycle; your ovulation date usually occurs 14 days after the first day you had your period, while your fertile days occur 4 to 6 days before your ovulation. It is best that you have sex during your fertile window to increase your chances of getting pregnant.
