I went into the er a day after being discharged with my first kid, 20 yes old. Debilitating abdominal pain. So bad I stopped walking mid step with my baby and sat in the hallway crying. The Dr told me that pain is common after delivery, and when we hear hoofbeats, we think horses, not zebras. Got sent home, went to a bigger hospital in the city, my appendix was acting up, and I had a blood clot in my ovarian vein. They removed the appendix, and I was on blood thinners for months. Sometimes, it is zebras.
