Pregnancy Confirmation: When to Take a Test & What to Expect

The optimal time for pregnancy confirmation and initial evaluation is six to eight weeks from the first day of the last menstrual period.

Why it may take longer:

• Gestational age may be difficult to determine in early pregnancy due to variability in the size of the gestational sac and embryo.

• Confirming a pregnancy prior to six weeks may result in a higher false-negative pregnancy test result.
