pregnant?

Renee
Ladies... What are your thoughts? According to a <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">pregnancy app</a>, I would be starting my 7th week today. 
I have NOT had my period in 7 weeks, and am experiencing a lot of crazy symptoms...
-Hard Tummy
-Cravings
-Starving
-Gained weight
-Nausea
-Fatigue
It all feels very different than period symptoms. 
I have NOT taken a test either yet. I feel like it could still be too early. 
Just wanna hear everyone's thoughts!!
