A condom slipping up, rimming and unprotected oral, none are risks. All include air and/or saliva. The slippage would mean the condom was still on the head of your penis. so, this is no risk. Duo at 40 days would be conclusive. You didn't need to test but you did. No risk, you don't have HIV and yes, move on
