How to compare methods

Three things matter: effectiveness (typical-use, not just perfect-use), how it affects your cycle and body, and how easy it is to use correctly. The most effective methods (implant, IUD) are the ones you can't forget to use.

Long-acting reversible methods (most effective)

Hormonal IUD (progestin): 99%+ effective, often lighter or absent periods, lasts 3-8 years. Copper IUD: hormone-free, 99%+ effective, can make periods heavier. Implant: progestin rod in the arm, 99%+ effective, 3 years, may cause irregular spotting.

Hormonal methods you take/apply

Combined pill (estrogen+progestin): ~91% typical-use effective, regulates and lightens periods, can ease acne and cramps. Progestin-only pill: good if estrogen isn't suitable. Patch / vaginal ring: same hormones, weekly/monthly. Injection: every 3 months.

Non-hormonal options

Condoms: ~87% typical-use, and the only method that also prevents STIs. Copper IUD: hormone-free LARC. Fertility-awareness methods: tracking cycle signs; effectiveness depends heavily on consistency and training.

Effect on your cycle

Combined methods usually make periods lighter, more regular, and less painful (the "period" on the pill is a withdrawal bleed, not a true period). Progestin-only methods and the hormonal IUD often reduce or stop bleeding. The copper IUD can increase bleeding and cramps. After stopping any method, fertility typically returns quickly (the injection can take longer).

Choosing with your doctor

Your medical history (migraines with aura, blood-clot risk, smoking, breastfeeding) determines what's safe. Bring your priorities β€” effectiveness, cycle control, hormone-free, STI protection β€” and decide together.

Frequently asked questions

What's a healthy cycle length?

Cycles between 21 and 35 days are healthy. Average is 28 days. What matters more than the exact number is consistency from month to month.

When should I track my cycle?

Daily, even if you only log the period start date. After 1-2 cycles, Luna's predictions become accurate. Adding mood, symptoms, and cervical mucus makes them sharper.

Is it safe to skip my period using birth control?

Yes, modern continuous birth control regimens are safe and supported by major medical bodies. The withdrawal bleed week was historical convention, not medical necessity.

Can stress mess up my cycle?

Yes. Chronic stress can delay ovulation, lengthen cycles, or stop periods (hypothalamic amenorrhea). Reducing stress + adequate calorie intake usually restores cycles.

How is Luna different from other trackers?

Luna runs entirely inside Telegram β€” no app to download. Predictions adapt to your actual data. Privacy-first: data never sold. Free for the first 89 days, then optional Pro.

When should I see a doctor about my cycle?

Cycles consistently shorter than 21 days or longer than 35, periods longer than 7 days, severe pain that disrupts daily life, bleeding between periods, or no period for 3+ months without pregnancy.
