How to Calculate Ovulation for Irregular Menstrual Period

Pinpointing when you ovulate is key to getting pregnant. Find out how to calculate ovulation for those that have irregular menstrual periods.

Calculating ovulation is a key part in getting pregnant. If you are actively trying to have a baby, you need to chart and track your cycles so you know when you are most likely to get pregnant. However, for a lot of women who have irregular periods, it can be a lot harder to chart your cycles and it can be really difficult to determine when the right time for you to get pregnant is. Something that most people don’t understand is that even if your periods are irregular, you can still be ovulating regularly. Today we are going to give you some tips on how to calculate ovulation for irregular menstrual periods. Claim Your 20 Free Pregnancy Tests – Click Here

Chart your cycle

First of all, you should try to chart your cycles on the calendar for a few months to see if you notice any patterns at all in the way that your cycles line up. Even if you don’t end up getting pregnant on your own, and need to see a fertility doctor, having a calendar with your cycles on it will really help your doctor to figure out what is going on with you.

Observe your cervical mucus

You can also keep track of your cervical mucus, although this is not the most reliable method and it can be a bit unpredictable. When your period ends, you will usually notice a few days with little to no cervical mucus at all. After that, your amount of cervical mucus will gradually begin to increase up to ovulation. When you are ovulating, your cervical mucus will be very much like egg whites, clear, stretchy and thick. The day that your cervical mucus is most like egg whites is the day of your ovulation. This is one reliable way to calculate ovulation, but it might take some getting used to.

Monitor your basal body temperature

Another way is by taking your basal body temperature daily. You can do this with a special BBT thermometer. You have to take your temperature every day, sometimes even for a couple of months before you notice a difference. When you are ovulating, your basal body temperature will rise by as much as a whole degree. While of course, this is a reliable way to determine when you are ovulating, it can really take some getting used to and is not as convenient as just using a calendar to track your ovulation based on your menstrual period. It is a good alternative way to determine your ovulation though, if your periods are irregular.

Use an ovulation prediction kit

You can also get a ovulation prediction kit over the counter at any drugstore for a good price, and you can use it to track your ovulation as well. These ovulation prediction kits are really easy to use and are much like a urine pregnancy test. If none of these methods work for you, you can always have your doctor do some simple blood tests for you to determine if you are ovulating or not. As you can see, there are ways to tell if you are ovulating even if you do have irregular periods.

    I took out my IUD on October 4th and since I have been having only 1 day I’m guessing cycles. I bled off n on for a few hours n it went away at night n did not come back. Am I pregnant and not know it or is just supposedly hormones? Even tho I had a non hormonal type of contraception

    Pls help..

    My partner and i are trying to get pregnant, but i have started a little late. I am 49yrs old but am fit and healthy. Due to stress sometimes my periods are irregular and my period was late, should have been on the 8th of January and it arrived on the 15th, we had regular sex throughout and up until the 30th of January i know i was ovulating on that day. I had to travel on the 30th for work and on the plane journey i had the strangest hot flush that i hav ever had, my face, body arms were burning, it lasted for around 5mins. since then i have a strange feeling in my lower abdomen like a mild period pain but without the period!!! most mornings i get a little bit of a hot flush but am generally feeling good. My Breasts are not sore, and this morning the pain has lessened we would love to be pregnant and i dont want to hope too much, as have been reading up and dont want to think it could be the menopause. I know without taking a test its impossible to second guess, and i have joined the pregnancy circle late in the game, its very overwhelming to think about. Any insight and helpful words would be a blessing to us.
