Should I take a test?

I'm not really sure when ovulation was becaus I really haven't had a full on period since the first off may, that wa my last normal period. May 29th threw June 1st I spotted. And since June 16 till now I have been ever so lightly spotting. 
Taking test... Always disappoints me since having children is a slim chance for me, getting BFN's literally make me cry. 
But the last two days everything I have smelt has made me sick. Only in the morning though. And I have been peeing nearly every 30mins. 
But then again I'm worried that it just be my meds doing this...
Help ladies?
