@writererin - I don't see my doctor until 10/11, but this is how my cycles were before BC. So, it could be my body trying to adjust from BC or it could be my body going back to "normal". I used to have 3-4 week long periods, with anywhere from 2 weeks to 4 months in between them.
That's crazy! I can't even imagine have periods or cycles that long on the regular. I hope your doctor at least has some good advice for you, or some non-invasive, not expensive, reasonable intervention that will help.
