My AF showed up exactly after 6m of my DD's birthday while I was still nursing. I was also actively trying for the second one after that, got few positives, but none lasted longer than 5 wks - naturally lost due to poor egg quality or insufficient progesterone (my guess, never found out why). Anyway, in the end, we did one more FET with 5 embryos transfered and I am now pg with our second - 21 wks along.
