I am 10 weeks 2 days and recently I have been feeling quite hot in the evening hours, I never thought anything of it until last night when I was really feeling the heat while laying down in bed. I took my temperature and it read 99.5 -100°F I used a termomoitor that you run across your forehead. I was wondering if I should be concerned about this and when/if I should go to the ER for it. Since it’s the weekend I cannot call my OB to ask for advice. And has anyone else experienced this during their pregnancy?
