Brief Answer:
False positive

Detailed Answer:

I read your query and I understand your concerns.

Following is my reply:

1) There is no way Vitamin B 12 would have lead to false positive pregnancy test.

2) False positive pregnancy test is common as this test has known levels of false positivity.

3) Other 2 tests are negative means you are not pregnant.

4) If you still wish to confirm please get serum beta hCG blood test to confirm the pregnancy.

Let me know if you have anymore questions.
