How can you be pregnant and not know?
An article published on Today.com told the story of Dannette Giltz who woke up one morning to the feeling of sharp pains in her sides and back. She thought it was a case of kidney stones because the pain was indeed severe and debilitating.

She was rushed to the hospital only to get the surprising diagnosis that she was pregnant. It doesn't even end there. It gets more interesting when doctors told her that she was carrying twins.

Dannette was prepped for labour, and she put to bed. She got the shocker when she got delivered of not just two but three babies.

Tell me, how do you explain being pregnant to full term with three babies without having a clue that you are pregnant? It's a mystery that would need more research to unveil and understand better.

If you have watched TV shows like MTV's "I Didn't Know I Was Pregnant", you would see other extreme cases of this condition.....
