Hi!
If you were my patient, I would want to do a confirmatory blood test so that we would be certain how to proceed. I would find it difficult to dismiss 4 positive tests, unless I knew that you were reading them incorrectly.
Hope this helps!

I've had the same thing happen to me. Took 6 hpt and all came back positive. I went to the docor to confirm the pregnancy but the urine test came back negative. I ended up getting a blood test to check for hcg and the next day the doctor called to tell me I was pregnant. I would ask for a blood test or wait a week and go back again for a urine test. It's possible that you're just too early and the docs urine tests may not be as sensitive as hpt.
You should probaly carry on as if you were. The tests are made to record a hormone you only have when you are pregnant. A false nagative is more common than a false positive and to have four false positives is very unlikely. Wait it our a week or two and take another at home test if its positive than go to your doctor and ask for a blood test which is more accruate that a urine test. hope it helps :)
