Ok. So I got a positive opk on Tuesday 14th. My temp didn't really go up too much the next day (It showed the normal 97.7 but then when I took it almost immediately after it showed 2 degrees higher 98.0. I went with my first one since I was unsure but have also heard to wait a minute because if you snore or sleep with your pouth open it can effect it...IDK!) Anyways, then the next day it was the same as the second time 98.0. So this morning it was 98.4! Is that enough to register as a higher temp? Also, anyone ever had issues with their BBT giving them two diff answers back to back? And by the sounds of those temps would anyone guess when the big O took place? Sorry this is my first month charting temps and I'm confused!
