Bridgette...thanks for the advice...I will try to take it when I first wake up....I'm afraid I'll have to throw out my temps if tomorrows is low....ay ay ay....
HI I saw your post. I don't knkow to much about charting temps yet but i am here for you.
It is very possible if you are taking something that effects your estrogen that it would effect when you would O. My cycles pre-m/c & pre-charting had always been 28 days, but now that I chart I do notice a change . . . but mine have also been affected by the different fertility meds I've been on. I've O'd on CD10 more than once.
If you wake up at 4, then just take your temp then. It doesn't matter if you normally take it at 4:30, you have a 1/2 hr (some say hour) swing either way. But the minute that you are awake and your brain activity starts, even if you are lying perfectly still, will slowly rise your temp.
