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.
