No clue... Don't want to get my hopes up

I have no idea what to expect after a mc. But I tested about a week after I stopped bleeding from my d and c(which lasted four weeks) and I had a slight line on my test. I didn't test after that because two weeks after I stopped bleeding I got my first period. So I figured my pregnancy hormones went away. I caved and took a test today at 13 dpo and about 35 days since my first period and have this light line. I don't want to get my hopes up because what if I still have hormone left? It is like over 2 months since my d and c but I'm not sure how long the hormone can stick around. Do any of you know?
