There are definite risks of birth defects when Accutane is taken during pregnancy.
Well, most of the defects will be observed on ultrasound scans done in the first and second trimester, but there is absolutely no way to know all of the birth defects.
There are some defects which might not manifest right until the baby is born, or even afterwards.
So there is nobody who is going to tell you for 100 % that your child will be free of defects.
It is a calculated risk that you are taking, if you continue the pregnancy.
All the best.
please feel free to discuss further.
