How can I find that my friend is pregnent?

Buy a pregnancy test. Does your friend want you to know if she is pregnant? If you both want to know, then you may buy an urine pregnancy test kit from your local pharmacy. However, the test may be falsely negative if done too early, and may need to be repeated in 1 to 2 weeks. If your friend does not want you to know, then confidentiality laws prevent you from finding out.
