Hearing you, my last cycle (2nd since m/c) was a week longer, and I thought I either O'd on day 14 or 21, got AF on day 35, so that backs up O'ing on day 21. I read that sometimes your body gears up for O but then drops back again. No clue how long this cycle is going to be, hoping it's closer to normal for me! The usual, but unsatisfactory answer, is that after m/c anything can happen, and it's normal. Sucks doesn't it?
