(NBC News) -- A new survey finds many women who suffer from severe migraines, avoid getting pregnant.
The Mayo Clinic polled over six hundred women with a history of migraine.
20% said they did not want to get pregnant because they feared their condition would affect their own health, and the health of their child.
However, evidence shows migraines improve in up to 75% of women during pregnancy. Most Study show migraine medications do not increase risk of birth defects.
Researchers say it is important that women with migraine get educated on the potential impact of migraine on pregnancies.
