An ultrasound examination would be the most useful diagnostic tool at this time to confirm the gestational age and viability of the pregnancy. Given the patient's history of irregular menstruation and uncertainty about the timing of conception, an ultrasound can provide an accurate estimate of gestational age and ensure proper fetal development. It can also evaluate for any potential complications such as ectopic pregnancy or fetal anomalies. MSAFP screening and amniocentesis are typically done later in pregnancy, and the nonstress test is typically done closer to term to assess fetal well-being. The patient's history of smoking may warrant additional counseling and interventions to reduce the risks associated with smoking during pregnancy.
