There are many types of gels and it is good to be able to specify what kind of gel it is. Use it according to the instructions, which will state whether it will delay menstruation or not. Generally, if a woman is using a gel to treat vaginitis, this gel will not delay her period and it has nothing to do with her menstrual cycle. However, if a woman’s vaginal inflammation is too severe, it can have a heavy impact on her reproductive system, which can not only delay her period, but also affect her pregnancy and even lead to infertility, and can cause pelvic pain and affect her health. Therefore, in case of vaginal inflammation, you should go to the hospital as soon as possible and use the right medication under the guidance of the doctor.
