If you are already taking a regular contraceptive pill, it is totally fine to keep taking it even after using Escapelle/Postinor. Actually, it is a good idea to stick with your regular pill schedule, even if you had to use the emergency one. Think of Escapelle/Postinor as an extra safety net, for when something unexpected happens. Your regular pill will keep protecting you against pregnancy, and using them together will not cause any problems. The important thing is to be consistent with your regular pill, so keep taking it as you always do.
