While 28 days is heavily cited, a scientifically normal cycle for adults actually ranges from 21 to 35 days. For teenagers, the axis regulating hormones is still maturing, making cycles of 21 to 45 days completely normal.

Cramps (dysmenorrhea) are triggered by prostaglandins—hormone-like lipids that force uterine muscles to contract to shed the lining. Higher levels of prostaglandins equal more intense contractions and pain. This is why targeted anti-inflammatory meds (NSAIDs) are effective.

Absolutely not. It is a highly sterile biological fluid composed of standard blood, uterine tissue, and cervical mucus. It is simply a natural shedding process, no more "impure" than sweat or tears. The stigma is entirely cultural.

The average volume lost is roughly 30ml to 60ml (about 2 to 4 tablespoons) over the entire period. Losing more than 80ml is classified as heavy menstrual bleeding (menorrhagia) and may require a medical check-up to prevent anemia.

Cups are often medically and environmentally preferred. While pads absorb, cups collect. Made from medical-grade silicone, they do not disrupt vaginal pH, contain zero bleaching chemicals, and can safely be worn for up to 12 hours.

This is a widely debunked myth (the McClintock effect). Large-scale data sets confirm that bodies do not emit pheromones to sync cycles. Apparent syncing is just mathematical probability—given different cycle lengths, overlap is inevitable.

Polycystic Ovary Syndrome (PCOS) disrupts the hormonal axis. It prevents ovulation, which means the uterine lining isn't signaled to shed regularly. This results in irregular, skipped periods, and elevated androgens (which can cause acne or hair growth).

Yes, it is medically safe. The bleeding you experience on birth control is a "withdrawal bleed," not a biological period. Continuous use to skip bleeds is frequently prescribed to manage endometriosis, severe cramps, or anemia.

Seek medical advice if you experience: bleeding through a pad/tampon every hour, periods lasting longer than 7 days, debilitating pain that prevents daily activity (a potential sign of Endometriosis), or unexplained bleeding between cycles.
