Could I be pregnant this early?

So my period is suppose to start on the 1st, but earlier this week I started getting cramps and some discharge so I just figured I started a few days earlier. The discharge was more like “spotting” for the next few days and it was really dark (sorry tmi). After googling some info I decided to take a pregnancy test and it came out positive. Could it be wrong? I was ovulating a little over 2 weeks ago. I’m just having a hard time believing I could be pregnant so soon!
