I'm a primary school teacher and I'm 7 weeks pregnant. My head teacher came to me today to say that she is obliged because of my condition to let me know that there is an outbreak of chicken pox in the school and I have to discuss this with my doctor. (She knows already because I'm taking time out of work to have an early scan due to a miscarriage last year). I'll ask the doctor when I go for my scan, but is this something I should be worried about? I had chicken pox as a child so I thought I would be immune. It's getting me a bit concerned...
