No AF and BFN

Cortney
My first day of my last period was 1/24 and last month I had very light spotting that started 5 days before AF was due so I waited and toke 2 BFN HPT so I made an appointment with my OBGYN the other day and urine was still BFN so she wanted to check my hormone levels before a HCG blood test and now I'm sitting here with the lab results and her office is closed😒 does anyone know what's normal and what's not? This is driving me NUTS!
