When Agent Morgan leaves the hospital going rogue, Garcia pulls up a map while she traces his cell phone. Although there are Bethesda-area parks named on the map (Glen Echo, Beech Tree, and Ayrlawn), the map looks nothing like Bethesda, MD. It looks more like a stylized map of DC, with some streets added or taken away.
Although it's great for building the tension, at 33 weeks, trauma to the mother that doesn't directly impact the baby won't cause a miscarriage. Particularly since they were at the hospital when it happened, the baby's life wasn't at risk.
By 33 weeks the baby is basically fully formed and able to survive on its own.
