Menstrual phase
Menstruation marks the beginning of a new menstrual cycle and occurs when the uterine lining, which had been preparing to support a pregnancy, is shed due to the absence of fertilization. This phase typically lasts between 3 to 7 days, although the duration can vary significantly from person to person. For women trying to conceive, understanding this stage is crucial, as it reflects hormonal balance and the body’s ability to reset and prepare for the next cycle.
During menstruation, levels of estrogen and progesterone drop sharply, signaling the body to shed the uterine lining. This process is often accompanied by symptoms such as abdominal cramping, fatigue, mood swings, and changes in appetite. While these symptoms are common, unusually severe pain, excessive bleeding, or irregular patterns may indicate underlying conditions like endometriosis, polyps, or hormonal imbalances—all of which can impact fertility and should be addressed with a healthcare provider.
This phase also offers valuable insights into your overall cycle health. The first day of your period is considered Cycle Day 1, making menstruation an essential reference point for tracking your cycle's length and regularity. Monitoring the timing, flow, and symptoms over several cycles can help you and your doctor identify patterns or abnormalities. For women trying to conceive, this tracking provides a clearer understanding of ovulation timing and highlights potential concerns, such as cycles that are consistently too short or too long.
Far from being a passive phase, menstruation plays a vital role in preparing the body for conception. It acts as a reset mechanism, ensuring the reproductive system is primed for the next cycle.
