Fever and pregnancy

I’ve been exposed to the flu a couple of times this week.. so I’m not all that shocked that I’m feeling unwell today.. took my temp at 10:00am and it read 98.5. By 11:30 it said 99.3... so obviously something is going on.. my question is, what is considered too high of a fever for pregnancy? I know mine is still low grade at the moment and I’m monitoring it every 30 minutes or so. Just wondering what I would need to seek medical attention for. Also, should I take some over the counter meds to lower the fever or should I just let it run its course.
