Faint positive ?

I had a dnc almost 7 weeks ago i noticed i was feeling a bit off so i took a test and saw a faint line ? Then i took the other one to makesure it wasn’t a bad test and it showed up the same . Can this be old hcg after 7 weeks ?! Or the start of something? Im asking for opinions… obviously im going to make an appointment so dont come for me lol . Just curious if anyone has experienced something similar.( i promise the lines are there lol just very faint)
