My close friend 34 weeks pregnant had major bleed yesterday and in hospital recovering they think it might be abruption 😵 now researching placental abruption Im really worried and crying my eyes out for her ? The doctors don’t seem too sure ? What may caused bleed ? They did scan and baby boy ok moving not in distress ? Does anyone have stories on placental abruption what happened to them ?
