Haallow Dear, Your two positive tests are more supporting the possibility of pregnancy. The two negative tests may be false negative. These tests if performed in the first week of missed period may give false negative results. Moreover, since you are performing the test at home on the overnight first morning urine sample, the hormones (hCG) in this urine are concentrated and hence the chances of more reliable results. When you go to the doctor, the urine you collect is a random sample which may have dilute hormones in the early stage of pregnancy. However, your second test with the doctor was on morning first urine sample. To get rid of the dilemma, I would suggest you to get Beta hCG test done which is very specific and highly sensitive. The results of this test are quite conclusive even few days before you miss your period. I hope this guides you to the better method. Dr. Nishikant Shrotri
