Question for those who have charted through 2 pregnancies?

[Braven05]

I'm just curious...always when interpreting my chart this time around I've gone back to my charts from when I was TTC my DD and I compare them. I look at my post O temps and say, they're not as high as they were when I conceived DD so I can't be pregnant. Is this accurate? Should I be comparing them? I know when I was pregnant for the most part my post O temps were around 98.6 - 98.9 and I'm just wondering if that's what I should expect next time I conceive or if it's different? Anyone chart through two pregnancies?

HI there. I charted when got pregnant with my DD in January 2011, but i didn't chart when i got pregnant last time. My temps in the months when i was TTC my DD were much higher than they were in the months before i conceived my last pregnancy so i think your BBT can change over time x

Thanks... I can't see why they would change but I suppose they could
