Lowgrade fever

Greer

Hey so I'm do for AF any time and I have had a low grade/elevated temp for 4 days now (did not take it before then) I'm running 99-98 degrees. I's this a good sign? I have read it can be elevated before af an go down before (don't know how soon before) but I'm almost positive this has never happend to me! My cycles are

33-35. On day 34 now. Think I ovulated on cd 20 or 21! I hope it's a good sign! Any help would be great. Thank you!
