Help?!

I'm just wondering if anyone can give me some hope here! I believe I'm 11 dpo today. I've had flu like symptoms. No nausea. Just stuffy head, body aches, runny nose, really hot. My right boob has had some sharp pains. & everyday since O I've had milky cm. I'm supposed to start my period on the 4th & I'm not really bloated, no AF like cramps just some pinching and only on the right side. I'm being really hopefully but I took a test this morning and it was a BFN. Been trying for the past 3 months. Any suggestions? Should I test tomorrow as well?
