I had sexual intercourse a few months ago and didnt get tested(stupidly). It was with someone I didnt know at all. I used a condom but it broke and I didnt realize it until like 10 minutes afterwards. I've looked around online about the various STD's and I show no symptoms of any. However, the only one I am worried about is HIV, since it has almost 0 signs. I read it takes about 6 months for it to be fully detectable. Should I take one around 6 months to be totally sure? Or take one asap???
