Line too light for 11 DPO?

As

Took two FR tonight. They both have a line and they’re pink in person. I took a FR paper test as well and it also has a line. I believe I am pregnant, but is this too light for 11 DPO? I’m asking bc my last two cycles I had chemicals, confirmed with blood work. I’m afraid this is another chemical. With my only child I had dark lines by 11 DPO. 😒
