Help!

Okay so I have been talking the Norg-EE birth control for quite some time until my doctor stop refilling my prescription. I tired contacting her through any means, except in person, because of work. So now my appointment with a new doctor isn’t until November 29 and I haven’t have birth control since! As of today I AM 6 DAYS LATE!!! Yes I’ve had sex before my last packet of birth control was done and after it finished (possibly a week before my period was supposed to happen).

I’ve googled the possibilities and it said that coming off birth control messes up your cycle for at least a month or two.

Should I be worried and take a pregnancy test?!
