I went to a sexual health clinic to get a full sexual health screen including a blood test. Test results came back all negative and i did not have any high risk sexual encounters in last 3 months. However, exactly after 11 days of my blood test i got cold. I do not have fever but having sneezing(very little), blocked nose, runny nose and small caugh for 3 days. And today (14th day after test) i had loose stools 1 time. I am very worried that somehow i contracted hiv from the clinic during blood collection. When i searched online i saw hiv ars normally strat after 10 days and include the symptoms that i am having. Can someone please help me here. Do i need to test again. Please help, thank you in advance.
