Patient: I recently took 2 pregnancy test and they both came out negative but I still havent got my period what does that mean?
Doctor: This is a very frequent question that we get asked about. For accurate results, pregnancy tests should be taken after yo u have crossed the estimated date of menstruation. Urine tests for pregnancy are most sensitive 2-3 weeks after conception. A blood pregnancy test is more sensitive and will be able to determine pregnancy even after 1 week of conception. Sometimes stress may also lead to a delayed period.
