TTC first late period help please!!?

Faith • Happily married. Ttc for 4 EVER!!!!!!
Husband and I have been trying for 14 mounths. I have totally missed my period today should be the last day. I've had cramps but.. No period. 
​9DPO I had what I believe to be implantation bleeding.. I've taken test every few days until I got another negitive 1st day after my missed period. 
​I'm feeling lost.. Want to stay positive but feel like I may be out with the negitive test. 
​My symptoms have been:
​Exhausted ( not just tired) 
​Had extermally sore nipplesnow they have chilled out a bit and my whole breasts are sore.
​That's about it! Anybody have any advise??
