Hello so in May of this year started dating a man casually and we have had unprotected sex since up until now I had a full check up in July and my HIV test came back negative he recently had a child and was tested as well and he was negative in between the time I had sex with another person however it was protected that happened once I went to the hospital because my blood levels were very low and I am anemic and the doctor wanted me to have a blood transfusion I have been having headaches nausea diarrhea but no fever I just wanted to know if there is a chance I may have contracted HIV or is it just anxiety and my anemia..
