I took a Frer yesterday morning. It had a slight line, I went to the doctor to confirm my line and my doctor suggested a urine test which came back neg. I was a little distraught and completely thrown off guard. Didn't expect that. Well I came home and took another frer and it's positive again. I'm so confused!  Below is a picture of both tests.
