Brief Summary
Low-dose aspirin started in the first-trimester has been associated with a decrease of preeclampsia, fetal growth restriction and preterm birth in high-risk pregnancies. Multiple pregnancies are considered a risk factor for all those adverse outcomes. The main objective of the current trial is to evaluate whether a dose of 80 mg of aspirin is associated with an improvement of birthweight compared to placebo in twin pregnancies.
