I read if your temperature doesn't rise post-ovulation to 98 and above, it's higher chance (40%) miscarriage rate, while if it does it's only 4% miscarriage rate. Also they were saying if it doesn't rise to 98 and up it means you have low progesterone (therefore that's why the early miscarriage). Has anyone heard this before or know if it's true? Im on 7DPO and my temp has NOT risen to 98, it was 97.33 this morning, but definitely ovulated 7 days ago (positive OPK and temp went up .5)
