Low grade fever = bfp??

Kallye
My husband and I had unprotected sex on September 8th; I am now 4 days late. For the past week I have had a low grade fever from 99 to 100. Last few nights I've had to get up to pee more often. Anyone ever experience these in VERY early pregnancy? Trying to wait longer to buy a test because I know as soon as I do I'll start my period.
