Vasovagal syncope (also vasodepressor syncope, neurally mediated syncope or neurocardiogenic syncope), a form of dysautonomia, is the most common cause of fainting ("syncope" in medical terminology). It is important to realize that vasovagal syncope and vasodepressor syncope are NOT the same. Vasodepressor syncope may cause long-term symptoms of nausea, fatigue, "wooziness" or dizziness, etc. Although it is particularly common (both historically and stereotypically) among young women, it is seen across all ages and genders and in otherwise completely healthy people. It is triggered by a number of factors, including prolonged standing, alcohol, fatigue, hunger, and anxiety. Vasovagal syncope is caused by low heart rate and blood pressure, leading to inadequate circulation. The reduced oxygen supply to the brain results in syncope, or temporary loss of consciousness. Individuals usually regain consciousness within a few minutes and their prognosis is good, although the syncope has a tendency to recur.

A vagal response arised from the effects of stimulation of the vagas nerves. The response includes a decrease in heart rate, blood pressure, a feeling of light- headedness (from the decreased blood pressure), and nausea. Vagal responses are caused by many things. They include suddenly getting up, pain, fear, excitement, immersion of the head in cold water, or stimulation of the coratid artery in the neck. Even going to the bathroom can cause the effect in some people.
Vagal responses can be useful, however, in rare conditions. Doctors can use them to treat people with some heart-rate irregularities. Often, they are one condition doctors must consider when determining the of fainting spells in patients. However, the are not often a cause of serious concern

I've never had it. Your contractions could possibly stimulating your vagas nerve which can cause decreased heart rate and blood pressure, light-headedness, and nausea. Question your doc when you go back to see him. Verbalized to him your concerns so that he can give you a more in-depth explanation. Ask him this same question if it can affect your delivery.

Oh, I thought it was how Bush answered questions from a crowd that hadn't been hand-picked by his personal staff.
