11DPO - faint positive?

Is this too faint for a positive?

I’m 11DPO and have had BFN’s every day. Except yesterday I had a faint positive on a cheap test and negative on a FRER / another cheap test. And the worst pain in my right hand side pelvic and tummy area. Today a bit of cramping... for reference I am due on AF on Monday and I never get any pre period symptoms until the day of.
