月經(jīng)時(shí)間不規(guī)律指月經(jīng)周期不規(guī)律，多數(shù)由卵巢排卵不規(guī)律引起。正常女性排卵是1個(gè)月排一次，月經(jīng)周期在1個(gè)月左右，有些患者月經(jīng)周期為1-3個(gè)月，周期長(zhǎng)短不定，稱為月經(jīng)周期不規(guī)律。如果患者月經(jīng)周期紊亂，經(jīng)期不正常，時(shí)長(zhǎng)時(shí)短，經(jīng)期延長(zhǎng)7-10天或者縮短，經(jīng)血量較多，屬于異常情況，應(yīng)及時(shí)到醫(yī)院檢查，明確原因及時(shí)治療。
