For some individuals, a single-day assessment of reproductive hormones like progesterone and oestrogen can provide valuable insights. However, for a comprehensive view of hormone patterns across the menstrual cycle, a 'mapping' approach may offer more depth. Typically, oestrogen levels follow a pattern: rising around ovulation and then decreasing. Progesterone generally stays low before ovulation, then increases significantly in the latter part of the cycle. Observing these patterns can provide insights into overall hormonal health and balance.
