Please tell me I'm not going crazy!

My husband and I have been TTC for the last 2 years, we just had a miscarriage about 6+ months ago.. And we currently have a 3 year old.. I'm late! :) I've been having some mild cramps on my lower left side& extremely tired.. If it wasn't for my child telling everyone that "mommy has a baby in her tummy" I wouldn't have even tested. I decided to take a test while my child was in the tub just a few minutes ago and I swear I see something!

Please tell me I'm not the only one!

I have another test and I'm debating on taking it in the morning or waiting a couple more days.
