Hi..... In a normal menstrual cycle, a balance between the hormones estrogen and progesterone regulates the buildup of the lining of the uterus (endometrium), which is shed during menstruation. If a hormone imbalance occurs, mentrual irregularities occurs..
Periods can be delayed for a single cycle or it can be delayed in every cycle. If the delay is in only a single cycle, the most likely cause is a temporary cause like stress... Consult Gynecologist for further evaluation....
Usually, a balance between estrogen and progesterone hormone is responsible for the building up of uterine lining which sheds during periods. However, period cycles may vary every month. Also, missing periods could be a sign of pregnancy.
Are you sexually active?
If yes, get a urine pregnancy test done before it's too late.
For now, vist a gynecologist for further evaluation and management.
