I was supposed to have my period earlier this month but I only saw a bit of faint blood, not enough where I needed to wear a pad. A couple of days later, I still had nothing but I decided to take a pregnancy test and I got double lines. 
I like how this one shows what two lines mean and what one line means right on the stick. It's easier to determine the results. My first thought was, "oh my gosh, this has never happened before". I just bought another pregnancy test pack to see if I'll get the same results. I bought a digital one this time. More likely than not, it'll confirm what the first test resulted. I am pregnant with my first child.
