positive?

Amanda
Yesterday morning I had a faint positive and I tested again today and got another faint positive, I believe. What do you think? I am 3 days before missed period. Also I had progesterone level done on day 21 and was 13 after Letrozole. My doctor added on a HCG qnt to my day 21 blood work and it was <1. Was the blood test too early? I am taking another one in 2 days
