How long after a B-ultrasound showing fluid in the uterine cavity will menstruation begin?

Ultrasound shows fluid accumulation in the uterine cavity. If the accumulation is minimal, it generally does not affect the menstrual cycle. However, significant fluid buildup may lead to reduced menstrual flow or prolonged cycles. The exact time of menstruation varies depending on the individual's condition, so only an approximate timeframe can be given—typically around 2 to 3 months. Detailed analysis is as follows:

Because the severity of uterine fluid accumulation varies among patients, it is difficult to determine precisely when menstruation will resume. In general, if ultrasound reveals only a small amount of fluid in the uterine cavity, the menstrual cycle usually remains unaffected and menstruation occurs normally according to the patient’s regular cycle. However, if there is a large amount of fluid, it may cause partial adhesions in the uterus, potentially leading to decreased menstrual flow or delayed periods. With effective treatment, menstruation may resume after approximately 2 to 3 months, although the exact timing varies from person to person.

Patients may also take medications under a doctor's guidance to improve their condition, such as azithromycin capsules, cefixime capsules, or tinidazole tablets. Patients must follow medical advice when using these medications and should not use them indiscriminately.
