I recently broke up with my boyfriend after 6 months together. When we were together we had sex without a condom 2 or 3 times (i'm on the pill). I'm clear and he told me he was too. Now recently he told me that in 1991 he had a hiv test cos he'd been promiscious in the past, the test came back negative. But i can't help but worry that they might have missed something, we're barely talking now so there isn't really anyway of asking him. Do they test HIV and AIDS by the blood and if i had other tests would it show up?
