Hi. Your question has been answered fully and accurately that there was not a risk from the towel. There is nothing to add to that and we are now closing this thread. Best of luck to you.

There's nothing else to add. As you've been told, you had no risk. It's not possible to get infected outside the body. You do not have HIV.
Towels don't transfer hiv. No one would want to put menstrual on blood on you. Anyways, you had no risk as the blood was exposed to air and cannot infect you. If you're sick, see a doctor, its not hiv.
