I've got irregular cycles (week 9 and no AF, and negative on a pregnancy test).
No idea of ovulation with the crazy cycles (I may try measure them next time my AF comes around). I've got a blood test appointment on Friday just to check everything is in order.
But till then, we're just DTD and seeing what happens. This is our first cycle to TTC though I wasn't exactly expecting cycles to be this bloody long.... 
Anyone in the same boat? Or have some positive stories of conceiving with irregular cycles?
