Disease description:

I’m just a few days away from my menstrual period, but I’ve noticed a slight increase in my body temperature over the past two days. Otherwise, I feel perfectly fine. I’d like to ask: Is it normal for body temperature to rise slightly a few days before menstruation?

Hello, Before menstruation, women often experience various symptoms due to hormonal fluctuations. One of the most noticeable signs is a change in vaginal discharge (leukorrhea). In addition to these changes in discharge, basal body temperature also rises—typically increasing slightly in the premenstrual phase. Concurrently, vaginal discharge often becomes more abundant. Therefore, appropriate self-care and hygiene are important during this time. I hope this information is helpful. Wishing you good health!
