I used FAM as a birth control method. I have two children. Both were the result of rule-breaking. However, my second was conceived while I was nursing and DS1 was waking a lot at night. I was only charting CM because I wasn't getting three solid hours of sleep before waking in the morning. My CM was really pretty wonky with my PP cycles (I only had four before getting pregnant again), so it was difficult to use it--and according to my U/S due date, I ovulated REALLY early the cycle I got pregnant.
I'm just wondering if anyone has a reliable temperature with less than three consecutive hours of sleep. DS2 is still young enough that he doesn't really have a consistent sleep/wake routine yet, so I don't know what he'll end up doing. But I'm wondering if I can get reliable temps with maybe two hours of sleep.
OR could I take temps in the middle of the night? Or does that not work?
Thanks for any insight.
