First of all, with menstrual cups becoming more and more popular, an influx of them are being manufactured. However, not all are of the same quality. It’s up to you to determine if you are willing to risk your health by choosing a cup that may have been made of questionable material or a cup that has been registered with its respected countries health & safety agency, (FDA – USA, TGA – Australia, Canada Heath, EMA – EU, etc). If you’re in doubt, visit the cups website, read reviews from other users who have experience with that particular brand, and seek information about them in forums or social platforms.
Many companies will have a size selection printed on the packaging based on your age or how many births you’ve had. However, these ‘rules’ aren’t always very accurate. One cup will NOT fit all. We are all different and so are cups.
Locating and measuring your cervix is one of the easiest ways to eliminate many cups that might not be comfortable or easy to work with your body. Cups come in all sorts of various shapes and sizes and while one might fit someone perfectly, it might feel uncomfortably long or be hard to reach for the next. You may also want to think about how light or heavy your flow is so that you can select a cup with a capacity to match. Even some shorter cups that are comfortable for a low cervix, have variations that allow for a higher capacity. These topics and more can be found at
