How do I know which size to choose?

This is your size guide. The O! Koek! menstrual cup is available in two sizes - A and B. It is important to select the right sized cup to prevent leakage.

To ensure you select the right sized cup, I would advise you to determine the height from your vaginal opening to the base of your cervix. Take one or two fingers, whichever is more comfortable for you, and place them softly inside your vagina until you can feel the base of your cervix with the tips of your finger/s. Remove and measure the distance with a tape measure. Select your ideal cup size by looking at the height.

Size A

O! Koek! menstruasie koppies - Groottes A en B 1

Size A is 42mm wide and 71mm in length including the stem. The stem itself is 17mm in length. This cup can hold 15ml.

Generally speaking, you can choose this size if you have a lighter flow and if you're not yet sexually active. I must mention that I am sexually active but my flow is light and the distance from my vaginal opening to the base of my cervix is not very high, so Size A works perfectly for me.

Size B

Size B is 47mm wide and 76mm in length including the stem. The stem itself is 19mm in length. This cup can hold 20ml.

Generally speaking, choose this size if you have a heavier flow, if you're already sexually active, or if you have given birth. Please however note the height of the cup.
