Positive pregnancy test after time limit?

Emily

Hi, I took a pregnancy test last night (12dpo) and there was a vvvvv faint line on it. When I looked at the test again this morning there is a pretty strong line there now. I know all about evap lines and all that but the line that has appeared on my test has colour to it and is the same thickness as the other line? I’ve read so many posts about people having this happen to them and they are pregnant! I don’t have a picture of the test last night but this is it now. I’m due on in 2 days and I would always be having pms symptoms by now and be cramping but I’ve had nothing like that.
