About This Period Flow Volume Tracker
This free period flow volume tracker is built on published clinical evidence and peer-reviewed research. All calculations run entirely in your browser — no data is sent to any server, and no account is required. Results are educational estimates intended to guide informed conversations with qualified healthcare or financial professionals.
Enter your cycle data above. For the most accurate results, track actual data over 3+ consecutive cycles rather than using averages. Hormone levels fluctuate significantly day-to-day — this tool provides population-based estimates, not a clinical diagnosis.
Hormonal Health Care in the USA
Hormonal health concerns are frequently undertreated in the USA. A full hormone panel (FSH, LH, estradiol, progesterone, testosterone, TSH, AMH) costs $200–$800 without insurance; most are covered when medically indicated under major insurance plans. PCOS affects 1 in 10 US women of reproductive age — diagnosis requires an OB-GYN or reproductive endocrinologist evaluation. Thyroid disease affects 20 million Americans; women are 5–8× more likely to develop thyroid conditions than men.
When to Seek Professional Guidance in the USA
See your OB-GYN or primary care provider if: your cycles are consistently shorter than 21 days or longer than 35 days, you experience 3+ months without a period (amenorrhea), you have significant PMS/PMDD symptoms that interfere with daily life, or you have symptoms of thyroid dysfunction. For PCOS, endometriosis, or PMDD, request a referral to a reproductive endocrinologist or gynecologic specialist.
