You were taking pills erratically when you first started your pills but you finally found a time that works for you how long do you need to take pills correctly before you can start having sex again?

Seven days. If you muck up on taking a pill (ie you forget to take it, or you take it late) you are advised to use other methods of birth control for seven days. The same applies here - take your pills correctly for seven days before trying sex without a condom.
