Is this a dye run?

I tested and the dye looked like it spread weird. this was after about 2 minutes

running to the shop now as I have no other tests. My little boy is only 4 months old and after 5 years we conceived him through <a href="https://glowing.com/glow-fertility-program">ivf</a>. so I dont know what to think.
