Unsure ?

So today I took a Pregmate pregnancy test which had a second line. Then I bought a first response soon after since that was my last pregmate. The first response has a small tint of color on the bottom part where the line would be but I’m not sure if it’s just a mess up. I have no clue this has never happened. Anyone else have this happen?? I have an irregular cycle so I have no idea when I would have ovulated. I stopped testing because I ran out of tests for ovulation. I’m so confused and lost. This is the first time I’ve received a second line on a pregnancy test since my last pregnancy. We have been trying for over a year.

All the same.

Same first response.
