I have an STD test tomorrow, I've never had one before so I don't know what it involves. It's a general check up for everything. My period just came, would I still be able to have the tests done? I mean what needs to be done to test me? Can they just take some blood/do a throat swab (in which case my period would not be an issue) or will they need to examine me more intimately (in which case it would be an issue)? It's too late to phone up and cancel so I don't know what I should do.
