There are many occasions where women wish to delay their periods, to prevent it getting in the way of their plans. The most common reason for this is when for example travelling. If you are taking a combined oral contraceptive, you can delay your period by taking 2 strips back to back (omitting the 7 day pill free period) however speak to your doctor first before doing this. If you are not on a combined oral contraceptive then you can take a hormone called norethisterone to help delay your period (if considered suitable after taking our safety questionnaire).

Progesterone in the body helps maintain the lining of the womb and therefore prevents shedding which occurs during a period. It can be found in many birth control pills, both the combined oral contraceptive pill and the mini pill. When taken as a higher 5mg tablet three times a day, it can help prevent and delay your periods.
