Hello ? Has anyone experienced this? I'm very worried about the threat of miscarriage, there was heavy bleeding but they didn't admit me to the hospital. They said everything is fine with the baby. Diagnosis: hypertonus myometritis and threat. Prescribed medication and sent home. A few days later, I started having discharge again (brownish). Went for an ultrasound, they said hematoma and happy that it's big. They prescribed the same thing as before, said it should go away on its own. It's awful, I'm still worried, it hasn't come out yet and I don't know what to do.
