Good morning! I was getting so excited because I finally had a positive OPK yesterday am. My temp yesterday was 97.20 and then it was 97.20 again this am when I woke up. I wanted to make sure that it wasn't just the memory or my BBT wasn't breaking so as soon as I saw the same temp I took it again without moving and it was 97.36. I know I'm supposed to use the 1st temp right?
