Hey, girl! I just said a quick prayer for you! You will be fine. However, the only way that you can find out if you have HIV is if you go and get tested. Check around in your area for a clinic. There are many clinics nationwide that offer free and anonymous HIV testing. Nobody has to know your results except for you. The only down side in your situation is that you need to wait at least 6 months after the date you think you may have received the virus. There is a window period during which the virus will not show up in your blood test - that's why you need to wait. Don't worry too much about this, but please protect yourself. Buy some condoms! Talk to your boyfriend about your fears. Make sure that he understands you and respects your wishes. Also, make sure that your relationship with him is completely monogamous.
God bless you!
