Confused.

So I had a miscarriage a few weeks ago. Like maybe 2 and a half weeks ago. Well I was taking tests until the line completely disappeared. Now I stopped taking them and just took one today out of curiosity and there is a very faint line. It's too faint to capture in a picture trust me I've tried. I took two tests both came back with a faint line. My question is is it possible to get pregnant that quick after a miscarriage. I didn't even bleed with the miscarriage. So I could have lost it more then 2 weeks ago but not sure. I didn't bleed, I didn't cramp. I still have not got my period back. The line was not even there a few days ago now it is. I'm super confused.
