Aspirin is generally best avoided during pregnancy. Don't be overly concerned if you inadvertently took aspirin in early pregnancy. A review of research studies and a large population study using information collected through a national registry in Hungary showed no increased risk of birth defects in babies born to women who used aspirin during the first trimester. Furthermore, another large study evaluating babies from over 19,000 pregnancies showed no negative long-term effects on intellectual development in 4-year-olds who were exposed to aspirin during the first 20 weeks of pregnancy.
