Worried. Risk of catching HIV with somewhat undetectable person.

[WilliameJ]

I'm a 20yr old male. About 4 weeks ago I broke up with my ex boyfriend. Afterwards he told me he was HIV positive(undetectable). We never used protection. We had anal several times, I was insertive and ejaculated each time. Him saying he was undetectable has been somewhat comforting during this time. However, 4 weeks later, today I have had runny stool, but I also had quite a bit of ice cream today after being Vegan for about 5 months. A few days ago I had a runny nose and some heavy coughs. How worried do I still need to be? and any option anyone has are welcome.
So far only the friend I live with now knows, I can't really tell anyone else atm. But any advice is welcomed, I'm worried for myself and those around me.

Also if he is undetectable then u have 96% chance that u wont catch it but still why he didn't tell you all this .I don't think its right . This isn't really right

At 28 days p24 antigen peaks during acute hiv infection then starts to decline.
You are a couple days past that so if you test asap with a 4th generation hiv test you could spare yourself 2 months of torcher.
A negative result now is unlikely to change at 3 months.

Thank you for your advice. I appreciate it. I will definitely get tested now as well as after the 3 month period. I hadn't thought about using a PrEP, so thanks for letting me know about that as well. I appreciate all your help and am braced for the next 2 worry filled months!

Since you have a confirmed unprotected sexual contact with a person that's HIV Positive I would suggest a HIV Test at 3 Months! Even though he's Undetectable there is still a Risk. Never go by Symptoms if your having Symptoms it's most likely something else the only way to know your Status is through HIV testing at 3 months. Also once you get you HIV test results in 3 Months you might want to ask about PrEP ( Truvada) with your doctor it's 92% effective in Stopping HIV infection if taken daily and used with a Condom!
