Have you already ovulated. If so, it is normal for your temp to be higher than your coverline. You aren't even supposed to have a coverline until you have ovulated. You can't calculate and make a coverline until you have had your thermal shift showing that you have ovulated.

I have seen many things say that cm is more important. This is because you get more cm before ovulation - especially like the day you are ovulating. But, sometimes it can be hard to tell what your peak day of cm is.

Temping is a real asset because it shows you (after the fact) when you have ovulated. Once your temperature incrases and consistently stays higher, then you know you have ovulated and can pinpoint the day of ovulation. So temping cannot be used to predict ovulation or to tell when you are coming lcoser to ovulation, like cm can. But it will tell you when you have already ovulated.

Hope this helps!
