Q. Did you ever hear of someone only finding out she was pregnant on the day of giving birth? My sister claims to have heard of this and we were wondering if this situation occurs often.

A. It hasn't happened to anyone I know personally, but I have heard of some cases. Unknown pregnancies seem to be most prevalent in teenage girls. It's possible that some teenagers may not be as familiar with the sexual development of their bodies and/or may be in denial about a pregnancy.
I have also heard of cases of overweight women not knowing they are pregnant because they don't feel or see much of a change in their bodies.
I don't claim to be an expert, but I don't believe that unknown pregnancy cases happen very often. I could only find rough statistics on the subject: about 1 in 5,000 women give birth without knowledge of the pregnancy.
Personally, I couldn't imagine getting through either one of my pregnancies without knowing! I had a smorgasbord of symptoms that provided an every-day reminder of my maternal condition. But, then again, I am very aware of my body and do love to lament about it!
