Low grade fever

Maria
Hi everyone! I'm new here as I just found out last week I'm pregnant with our first! After almost 3 years of trying my hubby and I are overwhelmed with joy and emotions it's kind of surreal! We are 6 weeks and 5 days and I've been a little worried that I have a low grade on and off fever. I don't feel sick just been dealing with nausea but I'm feeling a bit warmer than usual. I'll be cold and warm all in one day and sweat a lot during my sleep at night. Has this happened or happening to anyone right now?? Is it normal? I've been so worried about everything I hope it's just my hormones.
