My friend is pregnant and I've just found out my son has contracted chicken pox so I've told people who my son has been in contact with. Most people have taken it well except my pregnant friend who's 29 weeks who has basically made me feel guilty even though I'd no idea he had chicken pox when I met her last week. The spots have just broke out with no obvious symptoms or signs. She is basically saying she needs to go for special tests now ect as nobody knows whether she's had chicken pox before (her mum can't remember). I understand she's worried but I offered everything I can including my sons gp details so she could talk to him herself. What more can I do? My gp has reassured me that part of the blood tests performed in early pregnancy check your immunity to things like chicken pox and if she wasn't immune she'd be told. I feel like I've so much to worry about looking after my son without been made feel guilty for something I was not aware he had.
