First trimester

Yes. It's normal.. I also experienced the same thing. Turn on air con and fan already still super hot. Every night my husband cover blanket for me but I always tell him don't cover, I very hot. Just leave it. Hahaha! But if you take your temperature and it's above 37.5 °c then you must see doctor. If feel unwell just go see doctor. Hot and feverish it's different ya, do take note.
