manstruationis it normal periods which happens after 2 months
Answers: cycle that lasts longer than 35 days (arbitrarily) is called as oligomenorrhea. This may be physiological specially if occuring during puberty or near menopause. This is not of much concern if cycle is regular and not associated with other symptoms. One should consult a doctor if it is associated with obesity, hirsuitism, low fertility and cycles are erratic and irregular.
