Very High Luteal Phase Temps. Why?

Is it normal to have many of your temps after ovulation way into the 99.00 + range? All but one of the days during my luteal phase are all 99.00-99.60, even when they dip. Is that too high? I'm on CD 30 right now. I normally ovulate much earlier in my cycle but had a miscarriage and this is my first cycle since the miscarriage. I had a lot of spotting in the first half.
