fever, and chills?

I normally have a lower body temp of 97.2- 97.6 when I ovulate it usually gets to 98.2 - 98.6 ....I currently have a temp of 99.2; I take off my blanket then I'm freezing and back to hot again. My temp the past couple days has been around 98.0-98.3 
Because my current temp is almost 2.5 degrees higher than normal should I be concerned? I took ibuprofen for a backache I have and I figured it may break a fever if I have one. My fiancé is freaking out that my temp is 99.2 but I don't think it's that bad. ?
Af is due on the 7th and I've been getting headaches, backaches, emotional. Af is always clockwork and my boobs usually hurt 5-6 days leading up to af. 
Has this happened to anyone else before? I think I'm just getting sick with the flu or something, but reading some posts, some ladies said they felt like they had the flu before BFP. I think I'm over analyzing everything and it's probably nothing. I would like it to be a BFP but I fear I'm actually just getting sick 😞
