My temps are almost exactly the same as yours 97.4 – 97.8 pre-ovulation and 97.8 – 98.4 post-ovulation. During the day I am always able to get my temp over 98.6 usually even to 99.0. I hope I am on the right track, it feels like am. It will just take more time. I wonder if their is anything else we can do to help the process?
