Is it worth retesting?!

I’m 11 dpo and got a negative on First Response digital today. I’ve had preggo symptoms for the past five days or so, and ever-so-faint period cramps, which is not normal for me. Is it even worth retesting the day of my expected period? Is implantation out the window at this point??
