Period late

Bibi

I'm on CD37, and my period is like clockwork... comes on CD29. I'm experiencing all symptoms of my period. Can I be pregnant or my period is just delayed? I am gonna take a test later today, have to run out to the pharmacy. I really hope that i get 2 pink lines. I'm so nervous and don't wanna get too excited yet. I recently had a miscarriage in August.
