My doctor gave me a urine sample for a pregnancy test but it came back too diluted, I don't think I could be pregnant but what does that mean?

My doctor gave me a urine sample for a pregnancy test but it came back too diluted, I don't think I could be pregnant but what does that mean?

Another test needed: You need to do a home pregnancy test again as the previous doctor's test was inconclusive. In the "olden days" it was recommended to use a first morning urine for testing as it would contain a concentrated amount of HCG hormone. A pharmacy bought pregnancy test may be workable for you. If not, ask your MD to run a blood pregnancy test.

Could I still be pregnat if I took a urine pregancy test and it was negative?

Could I still be pregnat if I took a urine pregancy test and it was negative?

Trust the test: The first step is to repeat a home pregnancy test. They are quick, reliable and easy to do. If the test is negative then you are not pregnant. In that case you can monitor the cycle over the next few days and schedule a visit with an obgyn to discuss birth control. If the pregnancy test is positive then you will need to see an obgyn soon to be evaluated.

Will it affect the result if urine pregancy test HPT was taken while on active pills of birth control package?

Will it affect the result if urine pregancy test HPT was taken while on active pills of birth control package?

Pill pregancy?: Taking the pill will not interfere with the results of a urine pregnancy test. If you missed your period, you should get a serum pregnancy test from your provider or Planned Parenthood, which is much more accurate. Remember not to let more than seven days elapse after taking the last active pill of the previous package.
