it sounds like a virus hun! trust me theres a lot going around now i had a bad one last week!
those that are TTC usually chart they're temperatures with a basal thermometer and usually after ovulation if you are pregnant your temperature stays elevated until your expecting your period and will stay that way thru pregnancy. basal temps (when using for ttc or trying not to) are supposed to be taken right as you wake up in the morning before you move around or anything, and they're usually between 96 and 97.5 degrees and around ovulation go up .4 to .6 but everyone's different. your temperature seems a little high to be a pregnancy temp!
i think your just sick hun! don't forget to get plenty of fluids!
