Super super dark lines? Twins? 19 dpo 🤨

I’m 5 days late and these are my tests.. I know you can’t know your having twins until the ultrasound , I know ! But did anyone have these dark lines about 5 days after missed period ? Or r these darker than they should be ? I’m not worried at all or anything . Just wondering if anybody with twins had dark lines like these or does everyone have these after missed period
