Tested positive for covid last week, been symptomatic for 12 days now. for the last few days my temp is normal in the morning but develop low-grade fever later in the aft/eve, followed by many loose bowel movements (4+). is this still covid?

Yes most likely these are symptoms of COVID 19. It looks that you are doing better than before . Loose bowel movements will improve . Anti motility agents are avoided as virus is shed in stool and decreases the body burden of virus. You can try stopping dairy products for 4 weeks as some infections predispose to temporary lactose intolerance. See your doctor if not improving. Hope it helps.
