Faulty test?

I am 11dpo today. AF due today/tomorrow. I took a wondfo hpt this morning, and a thin pink line popped up as soon as the urine hit it. I was so excited, so I used another test (frer) and it was negative. Do yall think the first test was a faulty test? The line is thin, but, pink and shows on an inverted picture. Picture below:
