Bad evap lines on fr???

Journey

Okay so this is my 7th and 8th test in the past 3 days. There is literally nothing on the Walmart cheapie but the FR test has the pregnant line, and it’s gotten darker. Not sure what is going on but I just got back from Walmart with these test.

Recap: this past Thursday my level was a 3 or 4, so my ob wouldn’t consider me pregnant ofc but even that day I was getting BFP. Is this only me???
