Evap?

Hey guys!! I did something bad and looked at the test way after the time limit. Some background. I got pregnant with my 2nd 5 months after I had my first. I am 4 months postpartum now. I feel pregnant but haven't had sex in 3 weeks. I know that there are a lot of hormonal shifts at this point that may cause some symptoms. I took a test yesterday. The first picture is within 5 minutes of taking it. The second picture is like 21 hours later. I kmow... bad! Any thought on them? Is it safe to say I'm not pregnant??
