High Temperature

Car
Hello ladies this is my first month. I tried conceiving I ovulated a bout 6 to 7 days ago. And today I was standing up and I felt this heat wave / fever sickness hit me. So I took my temp it was 99.4 then I took it again within 10 minutes and it became 98.2. I never really take my temperature anyway as they say to log everyday like I should. Is this a good or bad sign of possible pregnancy?? Any thoughts ?? I also feel like I have a headache..
