guys please help me. I have made a terrible mistake. i helped homeless guy on the street, bought a magazine from him, he loooked like he felt on the ground some time ago, bruises and scratches,... i might have some residual blood on hands. right away (really max few min), I changed my tampon, without washing hands. Please is there any risk? I am so scared, I cant even eat. And dont know what to do with my husband and son now. Thank you very much for your help.
