Some pregnancy test dont work until after 1 week after missed period. But in some cases could even take longer.
Some woman never pass the urine hcg test but find the blood hcg to work for them, I think they say at least 2 weeks after conception the blood test works.
Having any of these symptoms??
Some early and later symptoms for most woman,
sore breast, tender breast. Some times lower abdominal pains, nausea, headache, swollen private parts, more sensitive privates, weight gain, frequent urination, back aches especially low back, sometimes new white discharge, montgomery glands on breast filling up(like pimple on areola), tired all the time, cramps in legs, more prominant veins in upper body especially breasts, sometimes swollen hands and feet, sometimes strange dreams, deeper sleep than normal. Dying of thirst.
Keep testing one week apart of go to dr and ask for blood test, usually more accurate and sooner than urine for some pple.
