Evap line or faint Positive?? HELPPPP

this is about a hour or 2 ago after the test was taken, I was seriously trying to hide it from my hubby so I kinda quickly looked a minute after taking and saw their was a "hard to see line" then stashed it until now. I had my period earlier last week, but was shorter and lighter than usual. however, I just had my first child 11 months ago, so my cycles are still on the mend. I'm thinking it may be a evap line since it seems off center, but I honestly don't know. (and I used condoms as a BC method, up until Monday of this week I started back on Nuvaring, and I started having some awful mood swings, and crying allllll the time, which is why I decided to test (for assurance) though my result is not 100% reassuring.
