Chicken pox infection in first 3 months of pregnancy can cause a slight risk of congenital varicella syndrome (CVS) It is characterised by birth defects.skin scarring.malformed limbs.smaller head.neurologic problems.and vision problems.or seizures Also chicken pox can cause baby to grow poorly in uterus or have abortion or even death So you have to decide... Even if you have had a abortion few months ago....the risk of this pregnancy having problems is there. Best option would be to get counseled by a gynec and go for abortion if you dont want to take chances. You are young and can conceive again...
