plan B contraception and copaxone

[downtowner]

While I was on copaxone I took plan B the emergency contraceptive on 24 th of september of this year. I got my period on the 28th and it has lasted until this day. I've taken plan B before and it has worked but neve while I was on copaxone. I carefully read the list of medications it may interact with before taking it and copaxone was not listed. I have an appointment with the gynacologyst on november 10th. Any advice would greatly be appreciated.
