Month by Month: What to Expect

Month 1 – Fast Relief

Thanks to its dual-action formula, Hey Sister! can be felt within 15–45 minutes of taking your first dose, as shown in the Australian randomised, placebo-controlled clinical trial on Khapregesic® . Many notice early improvements like reduced cramps, lighter bloating, and less reliance on painkillers in that first cycle.

Month 2 – Building Balance

By the second cycle, the changes usually go beyond cramps. Many women report more stable moods, fewer emotional dips, and steadier energy throughout their cycle. This is where you notice Hey Sister! supporting both the physical symptoms and the PMS mood swings.

Month 3 – Full Benefits

By the third cycle, improvements tend to become more consistent. That’s because menstrual health is tied to folliculogenesis, the process of follicle (egg) development.

Follicles take about 290 days to fully mature. The last 60–90 days are especially critical, when follicles influence cycle hormones means the eggs released today actually began developing three cycles ago

That’s why health professionals recommend committing to at least 3 months — it allows your body’s natural cycle biology to reset and respond.
