well, i had a non protected relation with my girlfriend. it was really brief, about less than 1 minute. Both were virgin, then did it twice with condoms, the last one we were in a hurry, so didn't used any. so i began having a fear, paranoia, etc ... We are 17 both.
i had an oraquick test at 70 days, and it was negative.
Well, i had one, in the morning, but i didn't swab it, just make it touch my gums about 4 times, then did the test, and it was negative 20 minutes later.
