Pregnant again after miscarriage? Faint positive?

Hello

I had a misscarriage last month and now this month I'm 3 days late. I took a first response early test this morning. In less than 3 minutes I saw what looked like a very very faint line,I had to look more than once to make sure my eyes were not playing tricks on me. It's so faint you can barely see it but it's there. I took a picture although my camera didn't take a good one,you can somewhat see it. I will post a picture,it's extremely faint,but I see something. I'm afraid it may not be safe since it's so faint. Any thoughts?
