Positive pregnancy test? Tubal ligation

Kelsie • Mama to 4.

I had a tubal ligation March 27 2018. So 16 months ago. My periods are now all over the place. Not sure if it’s because I am still nursing my 16 month old. Anyways, my last period was May 31! The other day I was extremely nauseated and decided to take a test. These are the two tests I took. Going to retake a pink dye tomorrow, but what are your thoughts.
