The two main ways you can verify if you are pregnant are to take a pregnancy test and then have an ultrasound verification.

Process For Pregnancy Verification

If you have missed a period or are experiencing pregnancy symptoms,
you will need to schedule an appointment for the next step. 

CHOICES uses lab quality urine tests to help verify pregnancy.

If indicated, limited obstetrical ultrasounds will help determine the viability of pregnancy and whether
it is ectopic or not.
