Fever at 6 weeks

Cora
Hi ladies, I was wondering if any of you can give some input on having a fever at 6 weeks and some days. 
I'm a "googler" so as you can imagine I'm freaking out a little here. 
I don't remember having a fever this early with my daughter. I had a miscarriage in May, not sure if those details are necessary or not but there you go. 
No cramping or bleeding, I just had a lot of cramping about a week or so ago around my left ovary for days but I read that was normal? I actually thought I was going to get my period because it felt like ovulation pains. 
I'd appreciate any feedback. My Ob isn't open on weekends.
