2. age 14 years or older and able to provide informed consent,
3. at least one of the following high-risk criteria: i) any prior pregnancy complicated by preeclampsia ii) current pregnancy complicated by chronic hypertension diagnosed before randomization (ACOG) iii) pre-gestational diabetes (on medication for diabetes prior to pregnancy, or diabetes is diagnosed prior to randomization with hemoglobin A1C of 6.5% or greater or abnormal 3-hour glucose tolerance test) iv) twin gestation (including higher order pregnancy reduced to twins prior to 14 weeks) v) chronic kidney disease vi) autoimmune disease (e.g., antiphospholipid syndrome, systemic lupus erythematous)

3. age \< 14 years,
4. involuntarily confined or detained,
5. considered as having a diminished decision-making capacity,
6. obstetrical ultrasound suspicious for major congenital abnormality, known or suspected fetal aneuploidy, fetal demise, or planned pregnancy termination,
7. participation in another trial that affects the primary outcome, without prior approval of the PI,
8. plan to deliver at an outside participating site with inability to obtain medical records,
9. monoamniotic twin gestation because of the risk of fetal demise and preterm delivery,
10. participation in this trial in prior pregnancy,
11. triplet or higher order pregnancy.
