Worried after 9 months exposure to HIV+ girlfriend
Hi started dating this lady in December 2011. We started having protected / unprotected sex by February 2012. Prior to that, she had assured me that she had just tested negative (test allegedly was conducted by her then doctor boyfriend). She she declined going for a test with me saying it would be repetitive. Over the subsquent months, we continued having unprotected sex. I did an HIV test on August 2nd 2012. On November 15th 2012, the unimaginable happened. She got pregnant by me and when going for the check up, she was diagnosed HIV+. I immediately did an anti body test the next day and it came back negative. Because, we had the last sexual encounter on 14th November 2012, I also immediately put myself on PEP (combivir/ Truvada) starting from 16th November 2012. About 55 days post exposure and 25 days post 28-day PEP therapy, I did another test and it came back negative.
Now, what are my chances that I will remain negative.? I am really stressed up over the last two months and life seems meaningless to me. Please advice
