When a big event like a wedding or holiday crops up, and your period is due at the same time, it can be very frustrating- it may affect how you feel physically and mentally, what activities you can take part in, and what clothes you can wear. In such situations, women quite often come to their doctor to ask how to stop a period from occurring. So, what are the options and do they work? Well there are actually a few, depending on the circumstances, the time-frames involved, your preferences and medical history. The three main ways are a progesterone tablet that you just take for a few weeks, the combined oral contraceptive pill, or a long acting contraceptive option. The last two options obviously need to be arranged well in advance, whilst a progesterone tablet can be started just before the expected period.
