Chicken pox effects during sixth month of pregnancy. Does it effects baby?

Probably not. Chances are good that no harm will come to baby, but timing is a factor. If you get chicken pox during first or second trimester of pregnancy, there's a slight risk (less than 2 percent overall) that your baby will get something called congenital varicella syndrome. The risk is highest (about 2 percent) if you're infected between 13 and 20 weeks' gestation. At 6 mos. Virtually no risk.
