Can Zovia 1/35th stop periods?

Izabel • Swimming and Art
I'm had a little  brown spotting earlier today but my period is two days late, there's no tissue or clumps in what little I have "menstruated."
I have been on Zovia 1/35th for almost two months now. 
I didn't have any pms symptoms ? 
And at the start of May the condom broke during sex. 
So is this the birth control or pregnancy
