Evap line or no?

Super confused about my test results. My period is three days late and I had unprotected sex around ovulation time so pregnancy is definitely a possibility. My period is normally like clockwork. I took a test the day before my period was supposed to come because I had some symptoms that weren’t my normal PMS ones and it was and still is a very obvious negative. No evap line or anything. I took a test this morning and I thought it was negative. After I didn’t get a positive after like 3 or so minutes, I just threw it away but I looked at it again after I got home from work and it now has a thin faint positive line. I know evap lines are a thing but everything I’ve read says that they are colorless or gray but my line is definitely blue. I know it was a few hours after initially taking the test but since there is color, can this be interpreted as anything?
