Abnormal bleeding during your period.

摘要

Periods are considered abnormal if they last more than seven days, have less than 24 days or more than 35 days between starting dates, or are very irregular or very heavy. Bleeding is considered very heavy if you have to change tampons or pads more than every one to two hours, or if you often pass clots larger than 1 inch. Vaginal bleeding in children or in women after menopause is always abnormal.
