Welcome to the forum and thanks for your question -- which came in while I was on the forum. Your English seems to be fine.
What exactly do you mean by "too early" for HIV testing? Reliable results are available as early as 4 weeks after exposure, depending on exactly what test (or combination of tests) is done. See the thread linked below:

In most of North America, under 1% of commercial sex workers are infected with HIV. And when a female has HIV, the average transmission risk for a single episode of unprotected vaginal sex is once for every 2,000 exposures. That puts your risk from unprotected sex at somewhere around 1 chance in 200,000 to 2 million -- i.e. the odds are very strongly in your favor.
Only you can decide whether this risk is low enough to resume unprotected sex with your wife now, or to wait for a negative HIV test. While I cannot say your risk is zero, if I were in your situation, I would continue unprotected sex with my wife with no worries about her health.
I hope this has helped. Best wishes-- HHH, MD
