Hi I Am 20weeks Pregnant And I Got Chicken Pox.I

Hi I am 20weeks pregnant and I got chicken pox.I had them as a child but still I was not protected.I had a scan after a week and the doctor said everything is ok.i had a blood test too and also was given some medicine called aciclovir. I am really worried about the baby I don't know what to do. I will have on other obstetric scan in 3 weeks time.No body can really tell if the baby is at risk.I read on the internet that most women had an abortion.I don't know what to do.
