Have you had these side effects before? I asked about this during my ER visit and the doc said it was just breakthrough bleeding and side effects from the pill. I have NEVER had bleeding in between periods from the pill before and I am taking the same pill(I had some leftover from my insurance). I am taking ortho tri-cyclen LO....and now into the 2nd pack am having bleeding even though it's not time for my period...not a lot but enough to be irritating and wear a pad. I also have tender breasts. NEVER had these side effects before...did anyone else have these issues when taking the pill...how many packs do you have to take before it quits?
