Flu symptoms early sign??

Katie
Af due on 10/1/16. Ttc number 1 and currently on cycle 5 ttc. I believe I ovulated on 28/12/15 so currently 6 dpo. I have had sore throat, mild headaches and aching body/sore skin for the last few days. Has anyone else ever experienced flu like symptoms and then gone on to get a bfp?
