I really, really urge that you don't use anything after the attempt. You're doing PLENTY as it is. If you really don't want to get pg then use a reliable method of birth control. The RepHresh won't do a thing other than kill sperm and if you wait 5-10 minutes before using it, there's no point because regardless of what they say on IG, the sperm flee the scene as quick as they can and are shortly out of reach of the effects of RepHresh. Even if it only takes you a minute to insert the RepHresh the sperm will be up inside the cervix anyway.
Have a read of this, it might help you make up your mind.
