To understand how light periods may affect fertility, it is important to understand the role of the menstrual cycle in conceiving. The menstrual cycle is divided into two main phases: the follicular phase and the luteal phase. Ovulation occurs in the middle of the cycle, usually around day 14 in a standard 28-day cycle.
During ovulation, the ovary releases an egg, which passes through the fallopian tube, where it meets sperm and fertilization occurs.
Regular menstrual cycles, with frequent ovulation, are important for conception. Menstruation itself is the shedding of the lining of the uterus (endometrium) when pregnancy does not occur. A healthy uterine lining is essential for implantation because the fertilized egg must attach to the endometrium to establish pregnancy.
Estrogen and progesterone related fluctuations are the primary cause of light menstruation. Estrogen plays an important role in the formation of the uterine lining and insufficient levels can cause thinning of the endometrium and light menstrual flow.
If hormone imbalances are severe enough to disrupt ovulation (such as polycystic ovary syndrome (PCOS) or thyroid disorders), they can reduce fertility.
