ABSTRACT
In their lifetime, 99 per cent of women will experience headaches and about one third of women will get significant headaches while pregnant, particularly in the second trimester. The majority of headaches (>95 per cent) in pregnancy are benign (primary headaches), but fear of a serious intracranial cause may lead pregnant women to present for review. Of those pregnant women with primary headaches, about two thirds will have migraine and one third tension-type headaches.
