Gonorrhoea and HIV
Thanks for your post.
It sounds as though for the most part the head of your penis was covered by a condom, meaning that the likelihood of HIV infection is negligible.
Gonorrhoea is commonly carried in peoples throats and around 90% of people who have gonorrhoea in their throats do not know they have it - ie they do not have any symptoms. So it is entirely possible and probable that your penile gonorrhoea infection came from the oral sex on you.
Syphilis in the heterosexual population in the UK is rare and I do not think that a likely possibility.
The tests you have had so far for syphilis and Hepatitis C - at one week - are too early.
So I think from what you have said that:-
1) you will not have acquired HIV even if the lady had it
2) you will not have acquired syphilis because it is very unusual in heterosexuals in the UK (note that the test you have had is too early anyway, but that does not mean that I think it likely you will have syphilis - I do not)
3) you ought to repeat the tests you have had so far at 28 days along with an HIV DUO test.
That will then give you certainty regarding all of this.
