Does sex affect my menstrual cycle?
Yes, sex can affect your menstrual cycle. For example, if you orgasm close to your period start date, it could come earlier. However, if you notice bleeding after sex often, please go to a doctor. There could be various reasons for this such as tearing, infections, or possibly cancer.
It's possible for sex to kick-start your period, but only if you have an orgasm during it and are nearing your start date. If you notice bleeding after sex, there may be another reason why. Infections, vaginal tears, ovulation, and cancer are some reasons you might bleed after sex.
