I had unprotected sex twice this yr, April and June to be precise. I had serious diarrhea of and on between June and August with no weight loss and now indigestion since September with serious weight loss but no constipation but I do get full by eating small amount of food. I only had malaria last week and it was severe with mouth sore but the mouth sore cleared within 3 days. I have been having the fear of contacting HIV for almost five months now, could these symptioms by sign of HIV infection?
