Yes, this acsually happened to me last year. And it happened to my sister and bestfriend!

It's never happened to me before but I have known it happen to a few people. If a woman is that worried about being pregnant it's best to go to the doctor I suppose.

It's never happened to me, and yeah I heard that too. False positives are possible, but they say false negatives aren't. However, it's become a lot common now that pregnancy test are delivering false negatives. I guess the best bet is if you think you're pregnant to go get a blood test done or something.

It is possible. What makes a home test come up positive is hGH (human growth hormone). Different tests measure different levels, but none can detect it as early as a test by a doctor. If you take the test too early, then you don't have enough hGH for it to register as positive. Some people never get a positive result until up to 8 weeks after conception.

It's never happened to me, but is totally possible.
