Vitimans/Eating/ and Pregnancy Tests

QUESTION

Dear Midwife,
I took a pregnancy test today. I am on day 27 of a usual 29 day cycle. The test was negative. A few hours before taking the test a ate a pretty big lunch and took a prenatal vitamin. This was my first trip to the bathroom afterwards.

Would or could this affect the outcome of the test. I have been pregnant a few times before, and I at times REALLY feel pregnant. I would think I am most likely not, but just wanted to know if eating and vitamins could have an affect on the outcome of pregnancy tests?

ANSWER

Nope. But taking the test first thing in the morning does make a difference, as the hCG collects over night.
