Symptom narrative

Was 5 weeks, 3 days pregnant at time of influenza vaccination; due date was 6/10/25. No noted complications in early pregnancy at that point. Miscarriage was determined via ultrasounds on 11/6/24 and 11/22/24. Estimated gestational age of fetus was around 6 weeks based on ultrasounds. Medical intervention (Cytotec then followed by D&C due to retained tissue) was used to manage missed miscarriage as fetus did not pass naturally after waiting a few weeks. Close timing between administration of influenza vaccine and pregnancy loss.
