Question:

I had unprotected sex with someone I just met. I know he sleeps around alot and I don't think he wears condoms regularly if at all. I was on my period when this happened and he did cum inside me. I want to know are my risks higher or lower since I was on my period and blood was involved? Or does it even matter?

My thought is since I was on my period the semen would be pushed out with the blood flow, therefore a lower risk? Please let me know ASAP I do plan on getting tested but I need to wait a few months so I get an accurate result.

The fact that semen, if infected with HIV, had direct access to your bloodstream would theoretically make you, or any menstruating woman, at higher risk for acquiring the virus. The idea of the blood pushing the semen out is interesting, but runs counter to what most experts say would be the more likely case. Anyway, it is good that you will take the test, and do remember safer sex for the future.
Good luck!
