Find your fertile window

You can only conceive during ~6 days each cycle: the 5 days before ovulation plus ovulation day. Sperm survive up to 5 days; the egg lives 12-24 hours. Track it with cervical mucus (clear, stretchy near ovulation), ovulation predictor kits (LH surge), and basal body temperature (rises after ovulation, confirming it).

Time intercourse

Having sex every 1-2 days through the fertile window maximizes the odds. You don't need to "save up" β€” regular frequency keeps sperm quality high. The two days before ovulation are the most fertile.

Prepare your body

Start a prenatal with folic acid 400-800 mcg/day at least 1-3 months before conception to lower neural-tube-defect risk. Aim for a balanced diet, healthy weight, regular movement, and limit alcohol. Both partners benefit from quitting smoking; heat and tight clothing can affect sperm.

Things that affect fertility

Age is the strongest factor β€” fertility declines gradually from the mid-30s. Irregular cycles (PCOS, thyroid issues), endometriosis, very high stress, and male-factor issues all play a role. A cycle app that learns your pattern helps you act on real data, not guesswork.

How long it usually takes

About 85% of healthy couples conceive within 12 months of regular, well-timed intercourse, and about 50% within 6 months. Not conceiving in the first few months is normal, not a sign something is wrong.

When to see a specialist

See a fertility specialist after 12 months of trying if you're under 35, or after 6 months if you're 35 or older (sooner at 40+). Go earlier if you have irregular/absent periods, known endometriosis or PCOS, prior pelvic surgery, or a partner with known fertility issues.

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.
