Oral Sex and Gingivitis

A few months ago I had a few casual encounters with a guy I met. We had unprotected oral sex and he ejaculated in my mouth one time. About 6 weeks after the incident I noticed several swollen nodes that were then confirmed by a doctor. It has now been 2 months and the swollen nodes have not completely gone away although they have decreased in size. Because my fear of HIV is so high I have been reading far too much about it online. Recently I have noticed that when I brush my teeth I occasionally bleed in one spot on my gums. My bottom gum line is also receding. I wasn't really aware of these changes in my teeth until now and it worries me that I may have put myself at risk for HIV. If someone has a slight case of gingivitis, or gingivitis in it's earliest stage is it possible to get HIV this way? Would the gums need to be actively bleeding?

Anyone?

Im not an expert

You cant really use symptoms to determine if you have HIV
IT is "possible" to get HIV through oral sex but its really really low and people say that makes it zero risk
You may not find answers on the internet completely reassuring
You can find places that give free testing, only way to know 100% and put your mind at ease if nothing else will...
This is the hardest part for me to confront. I am going to do it soon
