feeb - shift work could make it harder to chart if your starting times change, which I'm guessing they do. I guess though, as long as you temp straight after getting at least 3 hours sleep it should still work fine.

I'm in my 5th cycle after a m/c of a pregnancy that took 9 months to achieve. For the record we were not charting or paying attention to anything when we did conceive.... it all came as a bit of a shock as I really didn't think I would get pregnant due to prior TTC history and my age (40 then, 41 now).

I find temping really handy as you can predict when you O and also when to expect your AF from it. I usually get my AF 11 to 12 days after O and 1 to 2 days after my temp does a major dive. It's 12DPO for me now so if no temp dive tomorrow it will be time for testing.
