I voted "other."
We decided to TTC last spring, and I didn't take my May Depo shot. My cycles were really messed up for probably 8 or 9 months. I was charting, OPKing, the whole shebang, but my cycles were so screwy that I was getting more and more frustrated & heartbroken each month.
I stopped all the "formal" TTC methods after Christmas and only marked my periods on the calendar so I could see if my cycles were getting back to normal. I guess we went to the NTNP thing at this point; I had a lot less stress, and in the last 3ish months my cycles were regular.
So my short answer is we TTC for about 7 months after Depo, then we NTNP for about 3 with much success.
