Positive test?

Mattie • Married to the love of my life. Mother to sweet baby boy - 27 months. Pregnant with baby boy #2!
So I bought a bunch of little dollar store test and today I think I have two positive! But when my husband went to the store to buy a more expensive one it came back negative :( I'll retake them all tomorrow but I can't help but want to be excited, but am I setting myself up for disappointment? I have trouble tracking my period because it's not regular since I had my first child, but I'm guessing that if I were to have one it would be in this next few days or so. Also I know they are very faint but I can totally see them!! 🙈 lol!
