Should I get excited yet?

I’ve heard that any line is a positive, but I don’t know how correct that is. I’m trying really hard not to get excited. My <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says I should start my period tomorrow because my cycle is typically every 25-26 days. According to glow, I am 13 DPO. Anyone see anything? This was not first morning urine, I am going to test again in the morning. I really want to tell my husband, but I don’t want to get our hopes up.
