Confused

This is a cheap CVS brand test. I bought a two pack and took one this afternoon. It looked like this, but a bit lighter and now the line is completely gone! I took this one at about 3am because I'm so impatient and couldn't wait till morning. I'm 3 days late for my period and my period has come exactly on time for the last 6 months since I've had my daughter. I don't know what to think right now..
