So confused could I be pregnant?

The Frer is negative but the Walmart brand the blue line showed up immediately. I don’t know when my period is due Because I got on the depo on March 8th for the first time ever and then April 8th i started bleeding and I have been ever since. It’s been a total of 130 days. Well I was supposed to go back June 9th to get my 2nd depo but I didn’t because I didn’t like being on it. Well I didn’t have any bleeding for maybe 5 days and me and my BF had unprotected sex and he came in me. We aren’t actively trying but aren’t preventing. Anyways I don’t understand why the blue dye has a faint blue line that you can definitely see but the frer is negative. Please help 🤦‍♀️😢 here’s two different pictures of the blue dye it’s the same test then the Frer which is obvious negative but so confused
