If blood work confirms this to be the case, natural conception can be more difficult. What Causes a Shorter Cycle?
As a woman grows older, her menstrual cycle shortens. As the number of eggs available in the ovary decrease, their quality also declines. These dysfunctional ovaries lose their ability to effectively communicate with the brain.
Additionally, the brain needs to release more follicle stimulating hormone FSH to stimulate these abnormal eggs to mature. As a result, the dominant follicle is ready for ovulation very early in the follicular phase and consequently produces a short cycle length. In addition, sometimes bleeding can occur even when ovulation does not occur, and this may appear as shortened and irregular cycles.
Longer cycles are an indicator that ovulation is not occurring or at least not in a regular manner which can make conception difficult. What Causes Long Menstrual Cycles? Longer cycles are caused by a lack of regular ovulation. During a normal cycle, it is the fall of progesterone that brings upon bleeding. If a follicle does not mature and ovulate, progesterone is never released and the lining of the uterus continues to build in response to estrogen. Eventually, the lining gets so thick that it becomes unstable and like a tower of blocks, eventually falls and bleeding occurs.
This bleeding can be unpredictable, and oftentimes very heavy and lasting a prolonged period of time. There are many causes of oligo-ovulation, the medical term used to describe when ovaries do not grow a dominant follicle and release a mature egg on a regular basis. Polycystic ovarian syndrome PCOS , the most common cause for oligo-ovulation, is a syndrome resulted from being born with too many eggs. This can result in an imbalance in the sex hormones, and failure to grow a dominant follicle and unpredictable or absent ovulation.
Days: More than 7 days Ovulation Indicator: It is possible that there is a hormonal problem resulting in a delay in follicular growth or a structural problem in the uterus making the lining unstable. The menstrual cycle begins on the first day of your period, starting what is known as the follicular phase. A follicle is a fluid-filled sac in the ovary that will develop into a mature egg during this phase.
Once an egg reaches full development, it is released by the ovary during a process called ovulation. From there, the egg will travel down the fallopian tube on the way to the uterus in hopes of being fertilized by a sperm. Follicle-stimulating hormone, the hormone responsible for spurring egg development, also cues the uterus to thicken the uterine lining in preparation for a potential pregnancy.
While it may take several days for the follicular phase to be complete, there is only a hour window from the time an egg is released from the ovary where it can be fertilized to create a pregnancy. Once ovulation occurs, the menstrual cycle exits the follicular phase and begins the luteal phase, which will continue until the first day of the period.
At this time, the body also releases progesterone to mature the uterine lining to help a fertilized egg attach to the uterine wall.

Aimee Eyvazzadeh. With much of the current generic fertility advice based on the inaccurate assumption that a day cycle is standard and healthy, women are set up to worry unnecessarily, according to Eyvazzadeh. Since ovulation, which takes place halfway through a cycle, is so important for pregnancy, concerns can often stem from struggling to conceive.
After getting married, Kim Arseneault went off birth control and started trying for her first child with her husband. But after tracking her ovulation closely, it turns out the myth of the day cycle was to blame. She says the assumption that she was ovulating based on a day cycle not only caused feelings of self-doubt, but meant a slightly longer road to pregnancy. Alyse Gray started tracking her cycle because of a diagnosis of premenstrual dysphoric disorder PMDD , which causes severe pre-menstrual depression and anxiety.
