Menstrual blood made little circle on pajama. i didn't know and sat on chairs. did i infect everything i sat on? (if i have vaginosis or staph?)

Wouldn't worry: The germs that thrive in the vagina find the outside world harsh & deadly.They die soon after they might be left in those locations having lost the moisture/food that sustains them.Staph is everywhere anyway. The only way someone would become sick with them is to touch the area soon after & pass the germs to their body. The chance that that would happen is minimal.Handwashing is always a good idea
