Welcome to our forum and thanks for your question. Your English is fine.
Your combination HIV antibody/antigen test taken 30 days after your exposure is more than 99% conclusive. While the there are a very few cases of HIV which become positive between four and six weeks after exposure, this is substantially less than 1% of person to acquire HIV.
In addition, as I understand it, the exposure you described was a no risk event. When a condom is worn throughout vaginal sex, even if your partner did have HIV, this would be safe sex with no meaningful risk of infection. In addition, related to your receipt of oral sex, This is also safe sex. There are no proven cases in which a person has acquired HIV from receiving oral sex.
I hope the information I have provided is helpful. From the sounds of things, you have absolutely nothing to worry about in terms of risk for HIV. If any part of my response is unclear or there are further questions please use your act to follow up questions for clarification. EWH

Given the nature of your exposure and your negative test at 30 days I am confident you did not aquire HIV. If I were you, I would not bother to retest at 46 days. EWH---

Fourth generation, combination HIV antigen/antibody tests detect more than 99% of recent infections within four weeks of exposure. Very rarely (less than 1% of the time) infections may not give a positive test until between four and six weeks. As I said before, given the nature of your exposure, I would not worry and see no reason for further testing.
This concludes this thread. Take care. Please don’t worry. EWH
