Bleeding on BC

I recently began a generic brand of the Junel Fe birth control because I switch to delivery via the Pill Club. I am skipping the placebo pills and moving on to a new pack to skip my period for a while. For the last 12-14 days I have been consistently bleeding. Not very heavily but enough that it makes a difference to my every day routine. I have also had a few nights of bad stomach cramps though not very often. I was wondering if this is normal when adjusting to a new brand of birth control or if I should make an appointment with my gyno. Thank you in advance for any help. :)
