temperature and pregnancy please help

i ovulated on december 3rd. and i confirmed this with ovulation tests. i had intercouse december 2nd. Now, i dont chart my bbt because i dont have a bbt thermometer i only have a normal thermometer. but i take my temperature almost daily because i am a germophobe and am afraid of getting sick. my temperature never goes above 98.7. but yesterday, december 10th, my temperature was 99.1. and then today my temperature was 99.4. today i am 8 dpo. i have heard that raised temperature after ovulation could mean you conceieved. could my rise in temperature mean ive conceived??
