The shape of the menstrual opening varies according to the type and shape of your hymen, because the menstrual opening is part of it, so it may be visible in some cases while it may not be seen in other cases despite the menstrual bleeding, depending on the type, which can be as follows :

• A type of hymen that is completely closed. This type does not contain the menstrual hole from the ground up, and therefore it cannot be seen. Also, this type causes a problem because it does not pass menstrual blood, and therefore the woman who has this type of membrane needs a surgical operation to make a small hole that allows The passage of menstrual blood.
• A type of hymen that contains a small hole. This type may allow menstrual blood to pass through. Women who have this type may not be able to see the hole because of its small size.
• A type of hymen known as a detached hymen. This type contains two openings for menstruation, separated by a rubbery part of the hymen.

According to this information, it is not possible to determine if the menstrual opening is clear or not, as the matter, as we mentioned, differs from one woman to another according to the shape of her hymen.
