HCG level is 16.1

Vanessa

Went to doctor today for other issues but since I had a missed period on Sunday she ran a blood test. Got a result of 16.1, so now we have to retest in 2 days. I don't know if I should be excited or sad. I also had taken a hpt on Monday which I thought was negative but after test result today I looked at test again and there is a faint second pink line. Has anyone ever had this happen and had a successful pregnancy?
