I ovulated on CD22 which is may 30 2017 and i missed on my period (Last period was on May 9 2017).....we did BD through out my high fertile window and also the day i ovulated

i would like to know when is the best time to take pregnancy test ?

if the test is negative could i be still pregnant ?

Ovulating on CD22 is something should i be concerned about and talk to by dr?
