Too early?

Sabrina • Just going with whatever happens... Or trying too!
Im scared that it's too early to take a pregnancy test and I need help determining that, please! My last period was on July 6 and if I'm pregnant I think I conceived on the 27th. I've never really kept good track of my cycles though so I'm not sure when to test. Especially since glow said my period was supposed to start on the 5th. HELP!
