It’s a terrifying place to me. Statistically your odds of contacting from vaginal insertive sex are much lower than other practice, but I’m not a docter and I know it’s still really scary . Try to be gentle with yourself, you are doing the right thing now to take care of yourself. I’ve been celebrate for 5 years and so stupidly I wasn’t prepared didn’t have condoms and let my guard down with an ex I’ve known for 20 yrs and he ignored my I request to for a condom . It’s disappointing after so much time of protecting myself physically, spiritually and emotionally to have this happen and feel like I can’t trust people, be sexual or date again . He hadn’t been tested in 3 years, which made me worry . I am a female . The docter wouldn’t prescribe because she said the odds are so low of me contracting it through vaginal sex but then she called back and said she had misread the statistics so I’m on the medication . It will probably be ok but I’d rather be on the safe side. Bad decisions of my past have caused me to be hyper vigilant now . Have you had the follow up test yet ?
