Uterine bleeding can make a woman niddah even after menopause.

With staining, it is often possible to avoid becoming niddah by taking the same precautions that apply before menopause (e.g., using colored underwear and sheets, and waiting after urinating before wiping). Please see our page on stains for a detailed discussion.

However, if a woman has a flow of uterine bleeding, even she is postmenopausal and it is not technically a period, that would make her niddah. As a rule of thumb, a flow is defined as bleeding too heavy to be easily contained by a single light pantyliner over the course of a day. Please see our page on stains for further discussion.

The usual process for becoming tehorah (minimum wait, hefsek taharah, seven clean days, and mikveh immersion) applies when a woman becomes niddah after menopause.

Chronic staining can make it difficult to complete the clean days. In this situation, a halachic authority may advise a woman to perform fewer bedikot, and possibly also to wear disposable pantyliners.

A post-menopausal woman who finds bedikot uncomfortable should review the tips in the section on "Maximizing Comfort" on our page on bedikot. She may be advised to omit the moch dachuk and to reduce the number of bedikot during the clean days.

These halachot apply whether menopause occurs naturally or induced.

Medically, a woman who experiences uterine bleeding after menopause should see her doctor to determine the cause.
