Understanding the menstrual cycle

The menstrual cycle is a series of hormonal changes in the female body each month. It usually begins on the first day of the period and lasts 24 to 38 days (Merck Manuals, n.d.), although this can vary from person to person. The cycle is divided into four phases: the menstrual phase, follicular phase, ovulation phase, and luteal phase. These changes prepare the body for pregnancy by thickening the uterus lining and releasing an egg from the ovaries.

Here's an overview of each phase:

  • Menstrual phase: This is the first phase of the cycle and usually lasts 3-7 days. During this phase, the body sheds the uterus lining along with blood and tissue, resulting in a period.
  • Follicular phase: The follicular phase starts on the first day of your period and ends with ovulation. The pituitary gland releases follicle-stimulating hormone (FSH), which stimulates the ovaries to produce an egg.
  • Ovulation phase: The ovary releases a mature egg into the fallopian tube, making it available for fertilization. This phase usually occurs around day 14 of a 28-day cycle but can vary from person to person. Ovulation is considered the most fertile phase of the menstrual cycle, and tracking this for pregnancy planning is essential.
  • Luteal phase: The luteal phase begins after ovulation and lasts until the start of your next period. The egg travels through the fallopian tube towards the uterus during this stage. If fertilization occurs, the egg will implant itself in the uterus lining, and pregnancy begins. If fertilization does not occur, the uterus lining breaks down, and a new cycle begins.

Regular and irregular menstrual cycles

As mentioned, the cycle lasts from 24 to 38 days, with day one being the first day of the period. However, not all cycles are typical, and it's normal to have some variations in length. According to Merck Manuals (n.d.), only a minority of women, approximately 10 to 15%, experience cycles that precisely last for 28 days. Additionally, irregular cycles are observed in at least 20% of women.

Regular cycles have a consistent length, whereas irregular ones occur fewer than 21 days or more than 34 days (Cleveland Clinic, n.d.) Stress, diet, and exercise can affect cycle length (Cleveland Clinic, n.d.). Tracking these changes in the menstrual cycle can help individuals better understand their body's patterns and make necessary adjustments for optimal health.

 Keeping track of the menstrual cycle can help individuals identify any irregularities and bring them up with a healthcare professional. Understanding the body's natural rhythm can also help predict ovulation and fertility. For those trying to conceive, tracking ovulation can increase the chances of getting pregnant.
