How often do pregnant women get dvt?

1-2 per 1000. A DVT is not a particularly common issue with a rate of about 1-2 per 1000 pregnancies in low risk women, we take it very seriously because of serious health consequences associated with a dvt.
More than without pg. About 1:1000 women develop dvt's during pregnancy. The hormones produced with the pregnancy along with the pressure on the large blood vessels is the reason for the increased incidence.
