Normally the cervical opening is 6-7 cm away from the vulva, which is the distance of 1 finger. When a woman has vaginitis or cervical inflammation, she needs to place the medication deep into the vagina, mostly with the touch of a harder nodule deep in the vagina as the boundary, which is the cervical boundary, in order to be able to play the therapeutic role of the medication. If it is a woman who has not placed the medication in the vagina, usually when washing the vulva, do not touch the cervix with your fingers often, it can easily lead to vaginal inflammation and cervical inflammation. In some women, the opening of the cervix is not in the middle of the deep vagina, it may be on the upper or lower side, or the opening of the cervix is small, so it may not feel too obvious when touching or cannot be touched.
