I'd just not touch it for now and use the pencil.... if it's the first time you yoinked them out then they'll probably come back. It will take up to six weeks for them to re-appear. In that time, I'd reccomend "cruising eyebrows" - if you see someone with good brows, chances are they get them done by a pro. Compliment them and ask them, if someone does them, who is it and where can you find them. Unless you are a paid professional you will, guaranteed, overtweeze one side.
Get professional help so that you only have to clean up serious strays. If you MUST do it yourself... take one hair out at a time, taking lots of time to step well back from the mirror and re-evaluate the situation. Three hairs is enough for a bald patch.
