Hi,
Welcome to the ehealthforum and I am glad to help you out.To confirm the status of pregnancy, I would suggest you to get your serum HCG levels estimated since this is more specific than urine for pregnancy tests.
The HCG (it is a hormone) levels rise only in pregnancy and its presence will confirm the status of your pregnancy. If the serum HCG test is negative, then pregnancy is virtually ruled out. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided.
For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
