Your risk is low. Here are the reasons why:
1. Most commercial sex workers, even Asian women in San Francisco are not infected with HIV and few of them have STDs, it is bad for business.
2. You used condoms - they work.
3. While the cuts could, in theory get infected, in practice this does not happen. No risk from the razor cuts.
4. The timing of your symptoms does not suggest HIV or other STDs. They started too early and they do not come and go as you describe. You do not have ARS
5. You have no other symptoms.
Your anxiety is causing trouble for you. This exposure does not require testing for medical reasons however my sense is that you are worried about this. For that reason, go tested. At this time your tests for all STDs, HIV and hepatitis C, if you choose to be tested for it, will be reliable. While some will tell you should delay the HIV and Hepatitis C testing until 10-12 weeks have passed, given the very low risk nature of your exposure, at 4 weeks, your results will be accurate and came be accepted.
