Pregnancy is a time of 1/3's: One third of people get better while pregnant, one third will get an increase in symptoms and one third do not change during pregnancy. Personally I've read of a couple of women who have gone through a pregnancy with MG and both did OK.

Unfortunately, it is possible for the antibodies in your body to affect the baby, and at birth or shortly thereafter the baby will exhibit MG symptoms, sometimes severe ones. In that case, the baby is medically supported until the antibodies decrease, usually within a few weeks. I've read of one woman who had that happen and her baby had to be intubated, but went on to have a full recovery.

Any pregnancy would likely be considered "high risk" and you would need for your OB to work closely with your neuro. Of course you would probably want to be absolutely as stable as you can be before becoming pregnant, and some of the drugs can not be used during pregnancy.

Good luck with your decision.
