This is a great question! Let’s start out by saying that Sexually Transmitted Infections (STIs) can be transmitted in the following ways:
- Vaginal fluids
- Skin to skin contact
Someone must be infected and either exchange fluids, blood or have skin to skin contact with another person in order for an STI to be passed. If someone has unprotected vaginal sex while on their period, there is still a risk of exchanging blood, semen and vaginal fluids. If someone has an infection, then yes, there is a risk for transmission. There tends to be a higher risk since there is more blood present. There is also always a risk for pregnancy during unprotected sex. Ovulation can happen at any time, even when someone is on their period.
Since 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. Other than STIs and pregnancy, there is no other type of infection that can be transmitted while having sex when someone is on their period. For STI screening and free condoms, visit Teen Clinic!
