why is aspirin dangerous during pregnancy
During the first trimester, use of higher doses of aspirin poses a concern for pregnancy loss and congenital defects. Taking higher doses of aspirin during the third trimester increases the risk of the premature closure of a vessel in the fetus's heart. Use of high-dose aspirin for long periods in pregnancy also increases the risk of bleeding in the brain of premature infants. If you need to take aspirin during your third trimester of pregnancy, your health care provider will likely closely monitor you and your baby.
