Should I be worried about HIV?

Well two weeks ago I fooled around with my gf and I fingered her for a few minutes and after I noticed I had a small cut below my cuticle from where I bite form time to time. I dont know if I was bleeding but Im still worried. Shes still a virgin but has done everything other than , but now that Im worrying about it, Im getting a little uneasy. Now its been two weeks and Im starting to itch all over and Ive noticed little pimples where Im scratching, mostly on my back. Im also kind of congested and my throat feels bare but no signs of fever or swollen lymphnodes in my neck b/c I had my mom check. Should I be worried? or how long should I wait before I test with the HomeAccess test?
