Why is my cup leaking - 2nd part
Solutions: Anatomical cause - low cervix During menstruation the level of estrogen changes. This relaxes the cervix and is slightly lower than usual. Cervix is also more open, a little more than usual and may vary from month to month. It all makes menstruation blood flow away from the uterus. You do not see these changes during the cup insertion. But if the cup starts to leak, it is good to re-insert it and leave it a little lower. Anatomical cause - tilted cervix During the first few days of menstruation the cervix can be in different angle than usual. It may therefore happen that the cervix is not in the cup. Then, blood leaks down on the wall and out of the cup. It is necessary to remove the cup and re-insert so it completely closes the area around the cervix. Anatomical cause - general anatomy Every woman is unique and each uterus, cervix and vagina is different. It would be boring if we were all the same. In rare cases, it is possible that the cup will leak no matter how you inserted. For women dealing with leaks in the long term, and not even one idea how to inserted helped, so for them, unfortunately, there is not probably any solution. Anatomical cause - scars after childbirth It is possible that after you have given birth you have inside of the vagina any scars. If so, then the cup can leaks around them. So try to insert the cup lower or higher ... so that it does not lean on the scar. If it is possible try all possibilities how to insert the cup. The second option is to get a softer cup that adapts to the scar as much as possible. It is good to try all the options and to experiment. http://www.mujkalisek.cz/cs/blog/menstruace-a-mesicni-cyklus/proc-mi-kalisek-proteka-
