Q.

Abnormal Bleeding? Why Hysteroscopy is Key & Medically Approved Next Steps

A.

Abnormal uterine bleeding is best evaluated with hysteroscopy, a safe, minimally invasive procedure that lets doctors directly see the uterine lining and often treat causes like polyps, submucosal fibroids, adhesions, thickened lining, or early cancer. Most causes are treatable, and hysteroscopy enables targeted biopsy or same-visit removal when appropriate. Next steps vary by findings, from hormonal therapies to polyp or fibroid removal, with urgent evaluation needed for very heavy or any postmenopausal bleeding; there are several factors to consider. See the complete guidance below for who should get hysteroscopy, what to expect, risks, alternatives, and when to seek emergency care.

Q.

Brown Discharge but No Period? Why Your Body is Spotting & Medical Next Steps

A.

There are several factors to consider: brown discharge without a period is usually old blood leaving slowly and is often linked to normal cycle changes, hormonal shifts, or birth control, but it can also happen with ovulation or early pregnancy. Take a pregnancy test if there is any chance, track timing and symptoms, and seek care if spotting persists, is painful, foul-smelling, heavy, follows sex, or occurs after menopause. See below for important details on infections, PCOS, uterine or cervical conditions, and the exact next steps a clinician may recommend, which could change what you do next.

Q.

Is It Implantation Bleeding? Why You’re Spotting Early & Medically Approved Next Steps

Light, short-lived pink or brown spotting about 6 to 12 days after ovulation can be implantation bleeding, but it is less common than many expect and often mistaken for an early period.

See below for complete, medically approved next steps and key details that could change what you do next.

Q.

Why am I spotting 1 week after my period?

A.

One week after your period ends is the time of ovulation or release of an egg. You may get some lighter bleeding due to hormonal shifts that happen after your period.
