The answer to that is...yes. The only reason you're not supposed to have sex during treatment of an STD is that you still have a possibility of infecting your partner.
I'm positive you're not going to infect your hand with chlamydia.
She's right, and PLEASE wait the full 7 days to have any kind of sexual contact with anyone again, ok?
Otherwise, you'll need to be retreated and you could spread it.
