We'd like her on low-dose ASA during pregnancy, the intrapartum period and for six weeks postpartum (PP). If she has no other risk factors for thrombosis, I would reserve LMWH for the postpartum period only (i.e., enoxparin 40 mg qd for the first three weeks PP). We'd recommend fetal surveillance (detailed ultrasound in the second trimester, monthly ultrasounds in the third trimester, at least weekly testing in the last two months of pregnancy and delivery at 39 weeks). Although these women have an increased chance of poor pregnancy outcome, there is a good chance things will turn out well.
