Symptoms: Had protected se** with an extremely high risk woman. As far as I remember it was quick and the protection didn't break. I had several tests done: rna pcr at 11 days, combo elisa's at 26, 47, and 60 days as well as a standard antibody at 60 days which was offered for free with the last combo elisa. I was ready to move on until I started feeling symptoms at the 9 week mark. For the past two weeks I've had higher than normal body temperature but nothing serious; like maximum 37.8 from the mouth. What's odd is that the the increase in body temperature is not all day for the past two weeks- it seems to come and go at intervals during the day. Also, I have lost 5 KG in the last few weeks. ( It could be the past two months). I also have an abnormal toe nail fungus on both toes and a lymphnode in my neck that doesn't hurt but feels strange. How accurate are my results and is my stress and anxiety overblown to the point where it's causing me all these symptoms? Do I need to retest at 3 months? I was told combo tests are conclusive at 6 weeks post exposure. I'm also extremely confused with the whole window period thing. Is it possible for someone infected with hi*** to start producing antibodies and consequently symptoms at such a late stage? Or Do government agencies just state three months to be careful for medical legal reasons? I'm extremely worried and do not know what the next step should be
