What does this pregnancy test mean?

I had a chemical pregnancy which started 1st aug and bled for 15 days. I waited for a negative test which I got on 21st and 23rd August. The nurse did tell me to wait for 3 weeks for negative so I tested today (almost 3 weeks), and I feel like I can see a very faint line.can anyone else see it? I am pretty sure I ovulated again only last weekend. But now I am worried the other negative tests were wrong and I have already started trying again. Thanks in advance for any responses.
