Fever after ovulation? (101-102) harmful?

Ai

This question is twofold:

1) Can having a fever of up to 101-102 for 4 days be a sign of very early pregnancy? I had no other symptoms and was even diagnosed with “fever, unknown cause.”

I knew around day 2 or 3 I was pregnant last time and I ended up miscarrying. Not having the same symptoms completely, and I know a slight fever (98-99) is a common sign, but just curious if that high a temp could be too?

2) I know high temps can harm sperm, egg or embryo. Is it possible that this high of a fever for an extended period could have caused harm of there was anything?

Thanks y’all. Xoxo
