How to temp? Help!!!


So I’ve never taken my temp before so I was just wondering what this means! And I know I should have taken it earlier in this cycle but I didn’t. So yesterday 3dpo my temp was 98.6 and then today 4dpo (temping same time of day) my temp was 99.2! Is it normal to have it keep rising 4 days AFTER ovulation if you’re not pregnant? Not counting this as a diagnosis of pregnancy, just curious. Does it look like a good sign?
