I am confused

Courtney

Ok so I miscarried March 20th of this year. And I still haven't had my period. I just took a pregnancy test and the line looks to be there but extremely faint. What should I do? I am not stressed out or anything but like my period is so late and that's not normal. My miscarriage before this one my period came back and then I got pregnant almost a year later with this past miscarriage.
