Normal Menstrual Cycle may occur every 21 to 35 days
and may last two to seven days
. On the other hand, delay
in menstruation may be brought about by a variety of factors such as any illness, hormone changes, thyroid dysfunction, gynecological conditions and even stress, weight changes and too much exercise. If it persists or other symptoms occur, further evaluation may need to be done by your gynecologist. Take care and do keep us posted.
