Will the MCUK work for heavy periods?
Yes, the MCUK can work very well for heavy periods (or menorrhagia) because it collects up to three times more menstrual blood than a regular tampon (see Does the MCUK hold more than a tampon?). This means that you may not need to empty and reinsert your MCUK menstrual cup as often as you would have to change a tampon or pad.
If you are concerned that your periods are too heavy then you should talk about this with your doctor or gynecologist. Remember that the markings on your MCUK can be used to roughly monitor your flow, which may be helpful information to share at your appointment.
