I'm 17 weeks pregnant and I've fractured my coccyx. I can't move about much as it hurts, so I'm either laying on one side or just pottering around the house as the doctor has signed me off from work.  I know it might sound like a silly question but is not moving about a lot going to cause any harm to my baby? This is my first pregnancy and I don't know if I'm being over catious but I'm just worried! Thanks.
