When to take a pregnancy test
Wait at least a week after you’ve missed your period to take a pregnancy test. It's best to test first thing in the morning, when your pee/mimi is most concentrated.
Follow the instructions on the pregnancy test carefully.
A positive test means you are pregnant.
A negative test means you are not pregnant.
If the test is negative but you still feel you could be pregnant, contact your nurse or doctor, or Family Planning. You might have to do a repeat pregnancy test or a blood test.
If the test is negative and you don’t want to get pregnant, check out contraception options at Family Planning or with your nurse or doctor.
Is your pregnancy test positive?
