Is It True That Your Cycles Are Irregular?

A menstrual cycle that is either less than 21 days or longer than 36 days is considered irregular. 

If your cycle changes greatly from month to month, it may be called irregular. 

If you have a 23-day cycle one month and a 35-day cycle the next, your cycles are termed irregular.

Variations in cycle length have been proven to be more strongly linked to infertility, 

Then simply have a shorter or longer regular cycle. 

In other words, if your periods are somewhat longer than the average range but are regular, 

You may be less likely to have reproductive issues than someone whose cycles vary greatly but are consistently the same length. 

You shouldn’t be concerned if your cycles differ by a day or two from month to month. 

The longer the discrepancies are—five or more days—the more likely you are to have reproductive issues.

Detecting Ovulation in Irregular Cycles

If you’re ovulating sporadically, you’ll have to work extra hard to figure out when you’re most fertile. 

Ovulation can be predicted in a variety of ways. 

It’s possible that you’ll need more than one to figure out what the optimal time is for you to have sex.

Ovulation predictor tests are similar to pregnancy tests in that they need you to urinate on test strips, 

In order to detect when you’re most fertile. 

The tests, however, produce repeated “false positives” in some women. This is more prevalent among PCOS women.

Another disadvantage of utilizing these tests if your cycles are irregular is that you’ll need to use more test strips than usual. 

You don’t take the tests throughout your cycle; 

rather, you use them around the time you expect to ovulate. 

When your periods are irregular, your ovulation window may be longer than most women’s.

With Irregular Cycles, a Better Method of Conceiving

You could alternatively decide not to try to detect ovulation and simply have sex as often as possible throughout your cycle. 

Timing sex for pregnancy can be stressful for some couples. This eliminates the stress. 

When you get a positive ovulation test result, you won’t be trying to have sex. 

You’ll only have sex for the entire month (ideally, every other day).

You won’t have to worry about missing ovulation if you use this strategy. You’re more likely, 

To have intercourse on a fertile day if you have sex three to four times a week.

Modern Fertility Ovulation Kit | at-Home Test Helps You Identify Fertile Days, Predict Ovulation, and Get in Sync with Your Cycle, Includes Access to Our Free iOS App and Community | 20 Test Strips

$15.98  in stock
as of May 18, 2024 7:12 am


  • ABOUT THE PRODUCT - The Modern Fertility Ovulation Kit contains 20 ovulation test strips that allow you to track your luteinizing hormone (aka LH) levels each day to find your 2 most fertile days, predict ovulation, and get in sync with your cycle. Our Ovulation Test is 99% accurate at detecting LH, and each kit includes access to the free Modern Fertility iOS App and an invite to the Modern Community, where you can connect with other people with ovaries and ask fertility experts your questions.
  • HOW IT WORKS - Our affordable home ovulation test detects luteinizing hormone (LH) in your urine. When LH meets antibodies on the test strip, the test line darkens — the darker the line, the more LH there is in your urine. Unlike most other ovulation tests (aka ovulation predictor kits), you'll be able to match the shade of your test line to the corresponding LH level (kind of like those pH strips you played with in middle school).
  • HOW TO USE - Pee in a cup. We recommend testing in the afternoon. Dip the test strip up to the MAX line for 10 seconds. Let the strip sit for 5 minutes then match the test line to the color bar to find your LH concentration. Log your test on paper or in the Modern Fertility App with your camera to pinpoint your 2 most fertile days. Repeat daily to track your LH at low, high, and peak levels. The darker the test line, the closer you are to an LH surge.
  • ABOUT THE APP - The Modern Fertility App is an ovulation and cycle tracker that makes it easier to predict the 2 days you’re most likely to get pregnant. Our app allows you to scan and log your test to build a full picture of your cycle, track your LH levels so you can predict your LH surge, and see your entire menstrual cycle, LH test results, and fertile window predictions all in one place. If you’re trying for kids, you can also use it to time sex or insemination. If not, use it as an FYI.
  • ABOUT THE BRAND - Modern Fertility is a reproductive health company making personalized fertility information and support more accessible. Our fertility essentials - including at-home tests and tools - help you find power in your fertility info and get proactive about your reproductive health. Our Medical Advisory Board includes top reproductive endocrinologists, OB-GYNs, and fertility researchers. We believe that there is power in fertility info and we'll meet you where you are in your journey.
