Advice please!

So I had an MMC around the 10th-20th July (we didnt know exactly when I got pregnant) and a D&C on the 14th of August. I was told to test after a couple weeks to make sure it came back negative. Well I forgot and just tested now and it's come back very faint positive (barely visible). Should I still call my Dr? I feel like with how faint it is by the time I get to see my doctor it would be negative anyway.
