TTC frustration

A couple of Weeks ago my supervisor pulled me aside and asked if I were pregnant. She said I looked different that I had a glow. Although I played it cool with her, I was secretly hoping that I am. Today I wiped and had light blood on the tissue. I've started to get discouraged being that it possibly my period 2 days early. I'm hoping this is Implantation bleeding but I'm not sure. My hopes are low as of now. Any advice or encouragement from you ladies. How do you get through frustration during this time of TTC?
