Menstrual Cycle
Evidence-based answers to the most common questions about periods, cycle phases, fertility, and hormonal health.
Is It Normal for My Period to Not Come?
A missed or late period has many possible causes beyond pregnancy — including stress, weight changes, overexercise, thyroid disorders, and PCOS. A period is considered late at 5+ days past the expected date. If you've missed 3 or more cycles and aren't pregnant, see your doctor.

Blood Clots During Your Period — When to Worry
Small blood clots (smaller than a quarter) during your period are normal, especially on heavy days. They form when blood pools in the uterus before being expelled. Consistently large clots, soaking through a pad every hour, or periods lasting more than 7 days warrant a doctor's visit.

Your Period Has 4 Phases and You're Only Tracking 1
Your menstrual cycle has four distinct phases — menstrual, follicular, ovulation, and luteal — each driven by different hormones that affect everything from energy to mood. Tracking all four phases, not just your period, gives you a complete picture of your health and lets you work with your body instead of against it.

PMS or PMDD? Here's How to Tell the Difference
PMS affects up to 75% of menstruating women and involves manageable bloating, mood swings, and fatigue before your period. PMDD affects 3–8% of women and causes severe depression, rage, or hopelessness during the luteal phase that significantly disrupts daily life — and it requires medical treatment.

Can You Actually Get Pregnant on Your Period?
You can get pregnant from sex during your period, especially if you have a shorter cycle (21–24 days) because ovulation may occur soon after bleeding stops and sperm can survive up to 5 days inside the reproductive tract. The only truly "safe" days would require precise ovulation tracking — calendar math alone isn't reliable.

Is My Period Pain Normal? When Cramps Cross the Line
Mild to moderate menstrual cramps are normal and caused by prostaglandins that help your uterus shed its lining. But pain that disrupts your daily life, doesn't respond to OTC painkillers, or gets worse over time is not something you should push through — it may indicate endometriosis, fibroids, or another condition that deserves medical attention.

PCOS Complete Guide — Symptoms, Diagnosis, and Management
PCOS affects 1 in 10 women of reproductive age and is the leading cause of irregular periods and anovulatory infertility. Diagnosis requires meeting 2 of 3 criteria (irregular cycles, excess androgens, polycystic ovaries). While there's no cure, PCOS is highly manageable with lifestyle changes, medication, and ongoing monitoring.

Endometriosis — Symptoms, Daily Management, and Treatment Options
Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus, causing chronic inflammation, pain, and sometimes infertility. It affects roughly 1 in 10 women but takes an average of 7–10 years to diagnose. Treatment ranges from hormonal management and pain strategies to surgery, and the right approach depends on your symptoms and goals.

Fibroids and Adenomyosis — Heavy Periods Explained
Fibroids are noncancerous uterine growths affecting up to 80% of women by age 50, while adenomyosis occurs when endometrial tissue grows into the uterine muscle wall. Both cause heavy periods, pain, and pressure symptoms. Treatment ranges from medication and minimally invasive procedures to surgery, depending on symptom severity and fertility goals.

Ovarian Cysts and Pelvic Health
Most ovarian cysts are functional, form naturally during ovulation, and resolve on their own within 1–3 months. However, persistent, large, or complex cysts may need monitoring or treatment. Pelvic inflammatory disease (PID) and STIs can also affect pelvic health and fertility — early detection and treatment are key.

Fertility, Ovulation, and Your Fertile Window — The Complete Guide
Your fertile window spans roughly 6 days each cycle — the 5 days before ovulation and ovulation day itself. Tracking ovulation through cervical mucus, BBT, and LH tests gives you the best chance of conceiving (or avoiding pregnancy). Understanding your body's fertility signals puts you in control of your reproductive timeline.

Sexual Health and Your Menstrual Cycle
Your menstrual cycle creates predictable fluctuations in libido, arousal, vaginal lubrication, and comfort during sex — all driven by estrogen, progesterone, and testosterone levels. Understanding these patterns helps you work with your body, communicate with your partner, and know when changes signal something worth investigating.

Period Red Flags — When to See a Doctor and When to Go to the ER
Most menstrual symptoms are manageable, but certain signs demand medical attention — and some require emergency care. Knowing the difference between "call your doctor Monday" and "go to the ER now" could save your life. Trust your instincts: if something feels significantly wrong, it's always better to be evaluated and reassured than to wait.

Vaginal Symptoms — Discharge, Itching, Odor, and When to See a Doctor
Vaginal discharge is normal and changes throughout your cycle — clear, white, or slightly yellow discharge that varies in consistency is healthy. Symptoms like green or gray discharge, fishy odor, cottage-cheese texture, persistent itching, or pain during sex can signal infections like BV, yeast infections, or STIs. Many vaginal issues are treatable at home or with a short course of medication, but recurring symptoms, unusual bleeding, or pelvic pain warrant a doctor's visit.

Birth Control Myths — Does It Cause Infertility? The Evidence
Most widespread fears about birth control are not supported by evidence. Hormonal contraception does not cause infertility — fertility returns promptly after discontinuation for all methods except Depo-Provera (which has a temporary delay). Weight gain is minimal for most methods, cancer risk is a trade-off (slight breast cancer increase offset by significant ovarian and endometrial cancer protection), and there is no medical reason to take periodic breaks from birth control.

STI Screening — What Tests to Get, When, and What Results Mean
Regular STI screening is a routine part of reproductive healthcare, not a judgment on your choices. The CDC recommends annual chlamydia and gonorrhea screening for all sexually active women under 25, and HIV screening at least once for everyone. Many STIs are completely asymptomatic, so you can't rely on symptoms alone. Most STIs are curable or manageable with treatment, and early detection prevents complications like pelvic inflammatory disease and infertility.
