How does an irregular period affect fertility?

ovulation menstrual cycle and cervical mucus patternsHow does an irregular period affect fertility? My cycle ranges from 26 to 32 days, sometimes up to 45. What is considered as an irregular cycle?

Now, that’s a great question, because an irregular cycle may or may not affect fertility. let me clarify how…Your cycles can be lengthened but still be regular. Let’s say on average most people, even women with PCOS like myself, I know that my cycles were regularly lengthened.

In other words, they were regularly irregular because the usual menstrual cycle is the 28-day cycle. Some women however have longer, regular cycles so it’s really about finding out whether there is a pattern to your cycle or not.

Fact is, longer cycles are generally less problematic than shorter cycles.

With shorter cycles – anything under 26 days – the problem is that the lining of the endometrium may not have been prepared enough for implantation to occur. This situation generally called a luteal phase defect is when the second half of the cycle is shortened.

If shortening happens on the first half of the cycle before ovulation, that is usually less of a problem, unless of course it’s many, many days before ovulation. But generally, a shorter first half of cycle is not going to cause issues, as it can following ovulation. If the luteal phase is shorter than 11 days in any given cycle, that cycle is rendered infertile. That means that you absolutely need treatment in order to help balance that second half of the cycle.

We obviously use herbal medicine. We get some amazing results in regards to that, and nutrient supplementation can also help greatly. There’s some other tools – if we need to use hormonal support, we will use that, however we find that it’s not really that important or necessary because we can get really great results naturally.

Irregularity affects fertility from the perspective of knowing when you’re ovulating. But when you know what your body does and the unmistakable signs of fertility that you get before ovulation occurs, then you are much less likely to miss ovulation or to not be able to conceive because of a lengthened cycle.

Personally, in managing PCOS, I know my fertile signs. I know when my mucus peaks and when I’m about to be fertile. With my son, because I was doing all the things that I needed to be doing ‑ I was taking my herbs, taking my supplements, when my mucus peaked, I knew I was fertile straight away.

After quite a few months of treatment, when we started trying to conceive, we actually conceived pretty much right away, which was amazing, but really that’s because we were able to time it effectively because I had all the work that I had done months previously. That’s essentially what happened.

Irregular cycles are much less problematic than they really need to be,  and in my professional experience it is nearly always the case that there are other issues getting in the way, which have a cumulative impact on one’s ability to conceive.

When it comes to infertility we immediately look for and try to find the ultimate reason or “reasons” our ultimate result keeps alluding us but here’s the NEWSFLASH!… once it is all “said and done” the minor factors are really what get in your way and stop you from getting pregnant to have a healthy pregnancy to term and the healthiest possible baby.

The little sub clinical issues that your doctor often fails to point out when he or she glosses over a semen analysis report or a couple of pages of blood test results to categorically pronounce “it all looks fine” or “it’s all ok” whilst you continue NOT to be pregnant often is a clue. A piece of the puzzle, which in many instances unfortunately gets dismissed way too early in the investigative process.
