Temp over 100 for a few weeks?

He

I’m 26 weeks pregnant and have just been feeling so tired and achy and of course I’m blaming it on the pregnancy. I’ve checked my temp a few times over the past few weeks and every time it’s just over 100. Rite now it read 100.2 which isn’t really high and I don’t even know if it’s considered a fever. I haven’t had any other symptoms really and I’m thinking maybe it’s just because of the pregnancy? My whole system gets a little out of whack during pregnancy.
