Help please?! BFP or evap line

So I took a cheapy test since I don't feel like I'm going to be getting my period.... Instantly it had a BFN. After a little bit this second line showed up... Not sure if it's a positive or an evap line. I'm not getting my hopes up by any means. And I do plan on taking a test early in the morning tomorrow. 
Soooo help!!!
