If your viral load is detectable, HIV is in your menstrual blood and poses a risk of transmission. This is why it’s important to get tested frequently and to learn more about ART, which can decrease your viral load so that it is undetectable and untransferable.
If you’re living with HIV and receiving oral sex around the time of your period, it’s important to use dental dams (or cutting open a condom if you’re in a pinch) to protect your sexual partner. This is especially important if they have bleeding gums, any mouth sores/wounds or an inflamed/sore throat.
If you’re on treatment, not missing too many doses, and have an undetectable viral load, you cannot pass HIV.
