Sexually Transmitted Infections (STIs) can be transmitted in the following ways:
- Blood
- Semen
- Vaginal fluids
- Skin to skin contact
One person must be infected and either exchange fluids, blood or have skin to skin contact with another person. If two people have unprotected vaginal sex while a woman is on her period, there is a risk of exchanging blood, semen and vaginal fluids. If one person is infected, then yes, there is a risk for transmission. It tends to be a higher risk since there is more blood present. There is also always a risk for pregnancy during unprotected sex, even if she is on her period. Other than STIs and pregnancy, there is no other type of infection that can be transmitted during a woman’s period. Since the risk is high, it’s important to use a condom correctly, consistently and all of the time! Both partners should also get tested for STIs.
