Help!

Katie • Wife 07.25.15 💍 Mama 06.19.18 👧🏻 Pregnant with our 🌈 baby (08.2020)

I didn’t test out my trigger but did start to do pregnancy test on 12pt as that’s when I got my positive for my last pregnancy. The mine was there and I got excited. The next day, the line was lighter so I thought it was the Ovidrel (trigger shot) and decided to test it out. Now today the line is darker?!?!?What does this mean? I’m so confused!
