Pregnant?

Tiffany
I had a d and c almost 5 weeks ago.  Started having symptoms again an decided to take a test on 9-16, it was positive. My hcg was 5 at the doctors office yesterday and won't be back to check it again until next week.  The test I took today was darker.  If the line is getting darker shouldn't it mean I am pregnancy again and it's not leftover hormones?
