rose is correct. Urine pregnancy tests are not 100% accurate. I found at least one case in a medical journal of a woman who tested negative on three urine pregnancy tests (done in a hospital by trained medical personnel who presumably did it correctly) but was in fact 8 weeks pregnant (as shown by ultrasound). She DID test positive on a blood test though (I haven't heard of any false negatives with a blood test).
If you have missed more than one period and are still testing negative on a urine test, go see your health care provider for a blood test. If you do not have insurance and cannot afford to see a doctor, do an Internet search for family planning _________ (put the name of the state in which you live in the blank). You should find several links to free and low cost clinics that can help you.
you should get a blood test them pregnancy tests are bad sometimes trust me i know i was pregnant and had to find out through blood test
If you had any symptoms I would say you was but you don't so maybe you should wait or go see a doctor. I am also 2 months late and according to the due date calculator the conception date is a day that I had sex on but all my test have been negative but I have gained weight.
Many things can cause a missed or late period, pregnancy is only one of them. You should see your health care provider for an exam and tests to see what is happening.
you should go too the doctors
