Yup I have had haywire cycles but mine were shortening rather than lengthening. Mine became haywire during the months after IUIs and recently mine shortened after tcm. Maybe yours lengthened due to stress? Need to take time off to "sayang" urself during this TTC duration.Have u girls experienced haywire cycle after starting TTC-ing? I realised the past couple of mths I have been ovulating v late, on CD21 and then my period was late for 8days....on and off I have this problem. Previously my period was like clockwork, v on the dot. Duno why suddenly haywire.
