As long as you take your pills correctly you can have sex at any time without the risk of getting pregnant.
A break week does not cause you to become unprotected, only if you extend it. It wouldn’t make much sense to allow for a break week it it compromises your protection, look at the mini pill for example. It wouldn’t be a reliable method of birth control if it caused you to be unprotected for 14 days every single pill strip. The failure rate of birth control would be through the roof if that was the case.
