Pregnant?

My last period was September 23, I created the glow account because I'm hoping that I am pregnant but I tend to get my hopes up since I have an irregular period. According to the app I am 9weeks and 3days. I've been having symptoms sore breasts, nausea, and very very tired.I bought a pregnancy test today and was going to take it in the morning. I was hoping I could get some insight from other that may have the same issue or any advice.
