Help!

Went to obgyn today and confirmed urine test. It's going on three days of very very faint lines. She confirmed her urine test was faint but definitely positive. Today I missed my period. Digitalis are coming up negative still. I should be happy but I'm more nervous I'm going to have a chemical as my tests are not darkening! I did do a blood test today on my request(she wasn't worried). Will find out tomorrow. Anyone he faint lines for a while and everything be fine??
