Don’t tell them that... people who like NFP don’t believe those of us who tell them that having PCOS makes charting pretty much impossible. *rolls eyes* or at least mostly impossible. Last time I tried charting, if I’d been trying to avoid pregnancy my hubby and I would have had about five days of “safe” time that cycle.
(You didn't really have 5 days of safe time unless your cycle was incredibly short. You had 5 days of safe time that you recognized.)
Not only that, temp can be affected by so many things. I would get so many blips on my chart just due to waking up in the middle of the night to go to the bathroom! Temp can be affected by taking Tylenol, Benadryl or even a glass of wine before bed. Then you have to take into account your stress level, which pretty much goes through the roof trying to figure out NFP!
