What is a period?
A period (menstruation) a bleed which occurs every month, 2 weeks after ovulation and only when an egg has not been fertilised. During ovulation, the womb lining (endometrium) thickens in preparation for a fertilised egg and if an egg is not fertilised in 24 hours of ovulation, the lining is shed in the form of a period. This occurs every month between 21-28 days. Menstruation will generally last for up to 5 days. Day 1 is from the first day of your period and ovulation occurs between days 9-17 of your cycle.
How can a period be late?
Causes for delayed periods:
- Menopause, between ages of 45-55 years
- taking the progesterone only pill
- Sudden weight loss
- Polycystic ovary syndrome (PCOS)
A very common reason why a period can be late is if you have had unprotected intercourse during the cycle and you are pregnant. For late periods, it is always advised to do a pregnancy test. If it has been been less than 3 days since unprotected intercourse, you can take the emergency contraception to prevent pregnancy; please complete the general medical consultation and we can prescribe this for you.

You get a period every month as your progesterone levels drops and this sheds the womb lining. The norethisterone keeps the levels of progesterone raised, which prevents the shedding of the womb lining and hence your period is delayed.
