Denice • Married, PCOS, momma bear of 3 cubs

Long post warning! 10months ago I had a baby, and last week I had what I thought was my 1st AF since birth. Well, Saturday evening I decided to take a pg test because of some symptoms I was having. I got a vfl, and have had 3vfl since then. And then this afternoon I got bfp on a FR rapid results(last pic). I'm not sure what's going on. Do the rapid results not work as well? Could I be pregnant even though AF was just last week?
