Might be ok: You might be ok. You should talk to your doctor and your partner about this. Whenever you are in doubt, just ask your doctor. They will know more about your personal history than we will. Normally, when the treatment is 2 weeks long, you should finish the treatment first, to be sure the infection is completely treated. This prevents it from being passed on.
