Symptom narrative

Conceived on 11/24/2021, approximately 3 weeks after 3rd mRNA COVID vaccine (10/19/2021). COVID-19 infection confirmed 12/25/2021 during first trimester. On 3/3/2022, went into labor at 16 weeks gestation and miscarried. Placental pathology report described ?severely inflamed? tissue, with no bacterial or viral pathogens identified. Terminology used included chronic villitis of unknown etiology (CVUE). ER documentation was inconsistent: initially told pregnancy was normal, later labeled as ?septic miscarriage,? then retracted. Discharged after miscarriage. Pt still experiences break-through bleeding. Post-loss complication: On 5/15/2022 (second menstrual cycle after miscarriage), developed severe hemorrhage lasting >6 hours. This episode began approximately 2 days after receiving the 4th mRNA COVID vaccine (5/13/2022). Required ER evaluation due to ongoing heavy bleeding (saturating pads/chux pads). Hemoglobin/Hematocrit remained stable; vaginal ultrasound negative for retained products. Discharged once bleeding slowed. OB/GYN follow-up noted emerging literature on COVID vaccine and heavy menstrual cycles, although the severity of this hemorrhage was beyond typical reports. Possible contributing factors: (1) immune activation from recent COVID vaccination series, (2) confirmed COVID infection during early pregnancy (known to cause placental inflammation and vascular malperfusion), (3) severe placental inflammation documented on pathology. Etiology remains unclear: while labeled CVUE, clinical history suggests possible overlap with COVID-related placental inflammation.
