Does anyone know about this? Dd has had slapped cheek. I've had bloods taken and have active infection apparently. Obviously I'll now avoid pg women nine to twenty weeks as all the searching I've done says that's the dangerous time. But they've asked me in for scan tomorrow. Does anyone know what they're looking for? I really thought not a problem after 20 weeks. After a five day stay in hospital with a baby that wouldn't stay still I was kind of hoping for straightforward now. Due today.
