Is it too early?

Constance
I had a MC last month on May 21, the bleeding stopped on May 27. So a week of bleeding. I haven't had a period yet and have been feeling nauseous recently. My <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> app says that I'm 9 days late and should take a test but would I just be getting my hopes up doing that?
