I visited a prostitute. Now i'm afraid that i may have contracted a STD

Hi,

I'm from Belgium and i have a question.. I'll try to type English as good as I can.
I hope some people on this messageboard can help me, because i'm very stressed out.

I visited a prostitute somewhere last tuesday... She performed oral sex on me without a condom. After that, we had sex with a condom. Now i'm curious how much chance there is that i have contracted a STD like HIV, Chlamydia, Gonnoroe etc? Let's just say that there is a high chance she had one of those STDs, is it likely that i have one now? I called a Belgian Aids-helpline and they say that even if she has HIV/Aids, that i could never be infected by unsafe oral sex? Would you agree with that? And what are my chances for other STDs given she has those STDs?
I hope someone can answer my question because i'm really scared.... I hope my English was somewhat clear yo you.. I try really hard.

Thanks a lot for reading and answering my questions! I really appreciate it.
Greetings, Brock from Belgium.
