To buy menstrual cups is just like buying a new pair of boots. One should be aware of her feet size and which shape fits you perfectly and comfortably. This applies very well for menstrual cups too. There are only two things that you need to consider when choosing the right menstrual cup size.
1. Cervix Position
2. How heavy the menstrual flow is?
So, what is cervix?
Cervix is the cylindrical neck tissue in the lower part of the uterus that connects the uterus and vagina. The cervix's length varies from 2.5 to 5 cm. So if the cervix is longer then the vaginal canal will be shorter and vice versa. So knowing the position of your cervix will give better idea and help you choose between the short and tall menstrual cups.
But, How to find the position of the cervix?
Here’s a step-by-step guide to finding the position of your cervix:
- You should measure the position of the cervix when it is in its normal state which is before or after the menstrual cycle.
- Wash your hands and make sure fingers don't have any nails.
- Now try squatting or lift and place one of your legs on the toilet seat or brim of your tub.
- Once you're in the position, take a deep breathe and relax. Now insert the longest finger inside your vagina (lubes may be used).
- Try to reach and feel round, raised circle with a tiny hole in the middle. If you feel it, then that's the cervix.
So when your longest finger can reach the cervix, then you have a high cervix. For high cervixes, it is recommended to buy a longer menstrual cup.
If you reached the cervix until the knuckle of your longest finger, then you got an average cervix. For an average cervix, any type of menstrual cup would do.
If you reached the cervix above the knuckle of your longest finger, then you got a low cervix. For low cervixes, it is recommended to choose a best menstrual cup according to the menstrual cup size
