I fully read it, but obviously didn't get the part where you said that you finished the meds. I see the part where you ask if 5 days after use if the meds will be out of your body.... And that it is day 3, I assumed day 3 of taking the Monistat; not after completing it. I think the rule is 7 days after completing the meds. I'm no Dr but worked for a GYN. The box may have more info (if you have it) or maybe their website.
You obviously did not fully read my question.I FINISHED the treatment and I don't know how long to wait to have sex again.
Definitely use all the meds... You don't want the infection to return because of not taking the whole dose; or stopping too soon.
