Hi Krissy, im sorry to here about your situation, i do hope you have got the police involved and if needed got help for the siuation you are now in.
As for the risk, well 3 months is conlusive for HIV testing, although a test at 4 weeks is good news but their is not short cut to this, you will need to test out to 3 months.
You should speak with your doctor about you health concerns have, but in the mean time you need to not worry about this because their is little you can do about it.
Again i stress, you need to invlove the police if you have been raoed and get help if you need it.
I hope that helps
