I talked to the nurse today at my ob/gyn's office. I'm rescheduling my appointment for the end of August, and until then I'm just giving my body a break from the pill. I honestly have never had these issues with the pill before. The nurse kept calling it "breakthrough bleeding," and I was like, "Sure, if you want to call it that." Technically it is, since it started when it shouldn't have but it's heavy, and it doesn't just last a couple days, it lasts until I get to the start of a new pack... not my idea of "breakthrough bleeding." I'm almost bleeding more than I'm not.
Maybe giving my body a break will be a good thing. I don't know, it's worth a try. Until then, I guess we'll just use a different method of prevention and hope my body behaves itself.
