cramps and fever??

Amber • Husband and I have been ttc #1. Cant wait to have my own little family. ♡♡
I am having lower abdominal cramps that include: backache, achy body, chills and a fever of 102. I had the cramps yesterday that were just dull and annoying but today they have been horrible. This isnt implantation is it? im trying to wait to see if I need to go to the er.
