Up until a year ago I was on ortho-tri-cyclen for almost 4 years straight . I never had any problems except extreme nausea .

My doctor had me switching to yasmin, ortho-tri-cyclen low, tri-nessa, to try and get rid of the nausea .

Come to find out I had an ulcer so I got antacids and went back to ortho-tri-cyclen because it was the only thing to help with my skin .

So the problem is....
I've been back on ortho-tri-cyclen for 5 months now and since the beginning I have been spotting up to 3 times a week . Sometimes it is only for a couple of hours and other times for a day . It is light brown and then pink .

Does anyone know what the problem is here ? If it is the birthcontrol itself or something else ? I'd really appreciate it because my doctors can't come up with anything at all . It's 5 months, any side effects should have gone away from now.
