I agree, I think you should find other ways. Here's what I'm going to recommend.... stop temping. Chart your CM, CP and use OPKs. This will show a much better picture. Since you don't have a regular schedule, taking your temps won't be very helpful. Another thing you might want to consider is getting a CBEFM- Clear Blue Easy Fertility Monitor. I rented one from
THIS website. Only tough thing is you have to use FMU. For you I would say that would be whenever you wake up from your long sleep. HTH!!
