Today I found out my friend's baby has chickenpox (poor little thing) . I was playing with him on Saturday so think he was infectious then. I've not had it and so Drs just done a blood test to see if I have immunity. I'm 21 weeks pregnant. Just wondered if anyone else had experienced this? Such a nightmare, I'm really worried about my baba. I've just read I could have been immunised before pregnancy but didn't know that until now :(
