I am 17 years old, I had unprotected sex with a 23 year old man. He has lived in the USA for a year (currently now in Australia again where he was born) and toured with bands around the world living the 'rockstar' lifestyle, drugs sex rock 'n' roll etc. I know that he has injected drugs a few times but not often.
He has pulled out every time but we never used a condom (a decision which I regret and will never make again due to the paranoia it has caused me). 2 weeks later I got a sore and swollen throat that has not gone away (now 4 weeks later), I also have been feeling very tired and overall ill-feeling lately (which could possibly be due to the start of autumn/winter - but I'm not sure). I went to the doctor to get tested even though I knew it was too early and it came up clear for everything. I asked my sexual partner if he knew he had any bugs and he said no but he has not been tested in a while.
I have also recently found out that I am pregnant. I know that the chances of me having an sti are high, but what would you say about something as serious as hiv or hep? I am very scared and I know I've been so immature and irresponsible with my choices lately, but I need to know what the likely-hood of a serious sti is.
