Questionable test

So I should be 5 days late but I just had Mirena out last month so my dates could be wrong. I’ve had pink cm for a couple of days and then it stopped. This morning I had decided to test and I had a small amount of red blood when I wiped but nothing since. I used a dollar store cheapie and there is a test line. But I wonder if anyone knows do these tend to be less dark lines? I’ve never had a faint line. Does this mean I’m pregnant but maybe my dates are off?
