It is possible to take a pregnancy test at 2 weeks and 2 days pregnant, but keep in mind that the accuracy may vary. At this stage, your body might not have produced enough hCG hormone for the test to detect. It's recommended to wait until you miss your period or until you're closer to the 4-week mark for more accurate results. If you're unsure, consult with your healthcare provider who can advise you on the best time to take a pregnancy test based on your individual circumstances.
