Does fingering carry a risk of HIV transmission?

Hello doctor,

Three weeks ago, I met a girl in a club, and I was fingering her vagina for at least 30 minutes, but without any intercourse or kissing or anything else. A week after this, I started having gas in my stomach and feeling strange, and this continues to this day. Ten days after this exposure and after I drank a liter of milk, I had diarrhea. The next day, I ate, and 20 minutes later, I went to the toilet. Since then, I have not had such a problem, but whenever I am eating something, I have this feeling that I need to go to the toilet, and my stomach is "playing all over." But, I did not have any symptoms of diarrhea. Also, I never had a fever during this period. Five days ago, I started having a headache, and my nose was full. I was coughing like I had a kind of virus, and I did not know if it was correlated with the symptoms in my stomach. I still feel that I need to go to the toilet, but when I go, it is either the gas or the normal stool. On day 15, after the possible exposure, I went to a clinic, and I had an HIV third-generation test, and the result was negative. When I asked the doctor what kind of test it was, he mentioned to me the third generation, but enhanced, which is equal to or better than the fourth generation, and this is what the doctor told me. My worries are if I have been infected with HIV by performing fingering and only that, and if my symptoms are related to that, and if not, what else might be. Today, I am going to give a sample of my stool for culture to see if I have any viruses or anything else. Two weeks from today, my wife and I have decided to do in vitro fertilization, and therefore, I am worried if the above are interlinked and if I need to take any other action. Finally, my other question is linked to the latter. If I take any antibiotics now for my stomach, if they also find something in my stool and in two weeks, I need to give semen for in vitro fertilization. Is this fine, or will the antibiotics affect the quality of the semen? Should I do anything else with reference to my possible exposure to fingering?

Kindly guide.

Thank you, doctor.

What about the nose and my headache? Could this virus be related to stomach or flu? Also, my stomach has been like that for the last two weeks. I have tried to avoid dairy products.
