With my recent posts on cups, I have seen the same questions many times – one of which is “What cup should I buy?” You want to know that you are buying the right cup for you, and to be honest, it’s not a perfect science – but you can make an educated guess. Chances are, you’ll love your cup!
When I was first considering a cup, I chose based on the only cup that I had heard of – The Diva Cup. I was very pleased with my cup and it worked great for me. I have since tried several other cups (including Lunette, MCUK, & Sckoon) and all but one cup worked perfectly for me. When choosing your cup, keep in mind that they are all relatively similar, so there is no need to over analyze and stress out over the choices. Choose your cups with the tips below in mind and chances are you’ll love your cup.
Consider the diameter you need and the length you want and go from there.
Most manufacturers suggest that women under 30, who have never had a vaginal birth, should wear the smaller size they offer, while women over 30, or who have had a vaginal birth, should wear the larger size. This is a general rule – all women are different. For example, if you are over 30 and have children you may still have a strong pelvic floor if you’re active and you may feel more comfortable in a smaller cup. Know your body and make a decision based on that alongside the manufacturer’s suggestions.
If you know how high or low your cervix sits during menstruation, that may also play a role in the cup you choose. You can determine where your cervix sits by inserting a finger to find it. If it’s hard to reach (or you can’t reach it at all) your cervix is high and you’ll likely want a longer cup (like the Diva Cup, Lily Cup, or XL Me Luna). If you have a cervix that is easy to reach but not extremely low, you may be just fine with most lengths – though you may find that you prefer to trim or remove the stem from some (or all) cups. If your cervix sits just inside of your vagina (an inch or so inside) you have a low cervix and will want to choose a shorter cup (like the MeLuna Shorty).
I find that a shorter cup is my preference, but I also know many women that prefer a longer cup either for a higher cervix or because they can be easier to reach. Something else to consider is the stem. For me, the stem isn’t an issue since I cut them off, but your preferences may be different, so keep that in mind too.
Another thing to consider is flow. Many women think that they have a super flow, but in reality the average woman has a moderate flow with studies showing a range from 30-120 ml (or 2-8 tablespoons) for their entire period. I personally know women who have a “heavy flow” and love their cup – so if that’s your flow, a cup can work for you! I suggest choosing a cup with a higher capacity, though like many women you may find that a cup lightens your flow.
Last but not least is cup firmness. Generally speaking, larger cups are a bit more firm than their counterparts. A firm cup will pop open easier. If you have a very sensitive bladder, you may want to look for a softer cup.
The table below is a size comparison for several brands of cups, the first set are brands that I have personally used (testing does not equal endorsement). The cups below are all made from silicone, with the exception of the Keeper (Rubber) and Me Luna cups (TPE). These cups range in price from about $20 – $40 – and they are well worth it!
