It is likely that, from time to time, you will experience heavier than usual bleeding during your menstrual period, but it can be hard to know if this is normal or if your periods are heavy compared with other women. Heavy menstrual bleeding (HMB) can be a serious and debilitating condition.
It is defined by the impact it has on a woman's physical, social and emotional quality of life, for example if your monthly period limits your normal daily activities, or affects your role at work.
Are using an unusually high number of tampons or pads, for example if there is enough blood to soak a pad or tampon every hour for several consecutive hours
Are experiencing flooding (heavy bleeding) through to clothes
Need to use double protection, i.e. tampons and pads together
Are experiencing night time bleeding that requires you to get up to change pads or tampons, use extra protection at night and / or change your bed sheets
91% feel HMB impacts their ability to perform sport and fitness activities
80% feel that their heaviest bleeding days affect their performance at work
68% do not tend to participate in social activities when their period is heavy
However, in up to 60% of women with HMB, no underlying cause is found. This means that many women can be treated by their GP.
Side effects should be reported. Reporting forms and information can be found at https://yellowcard.mhra.gov.uk
You should also discuss any side effects you are experiencing with your GP or pharmacist.
