Trying to conceive

Hello, I’ve been trying for a baby for about 6 months. About a week ago I took a pregnancys test I left it for abit then came back to see the results I could see a faded line. A week after that I took another test and that one came out the same I could see a faded line. (When ever I’ve took a test it the past it’s always been negative) after I took the last pregnancy test I started bleeding but I’m not due on my period until the 22nd of this month. I’m really confused has this happened to anyone else.
