They do: Excepting a defective test, or not following the instructions, home pregnancy tests work very well, for everyone. There are not people who can be pregnant and have negative test. One common source of error is testing too early, but with 2 missed periods that doesn't sound likely. There are many reasons for missing a period without pregnancy. Good wishes to you.
