I was pregnant after being diagnosed with MG a year prior. I had a wonderful healthy baby boy who has had no issues related to MG in his 3 years. I will highlight certain features from my experience that may help you:
-I had monthly scans at the high risk perinatologist, made my OB feel better about something they had no idea how to deal with. Eased my mind to see the baby doing healthy each time.
-When he was born he did spend a week in NICU but that is due to his being born a month early for unknown placenta previa which had nothing to do with the MG
-the OB, pediatrician at hospital, nurses all were on extra alert to be on the lookout for any issues from him after birth such as issue breathing, weakness, etc. If anything he was strong, he kept pulling out the nasal cannula(air) and other tubes.
-I was told by my neuro NOT to let them use a certain type of saline IV which I do not remember now but at the time I let everyone know(hospital, ob, neuro, etc) and also carried around a list of meds to avoid for MG with me at all times. There are some that can have more adverse reactions depending on each individual. I personally cannot have anything in the quinolone antibiotic family or it makes me feel awful. I do not come here often but if you have any questions I have it set for members can email me and will try to answer. Good luck and honestly, the MG side effects almost dissappeared during my pregnancy. That part was awesome and apparently it does happen to others out there with MG. I have not been on a continual dose of mestinon since mostly due to stubborness and hating the mestinon side effects. I just take it as needed here and there which is okay with my dr. Currently having an episode which prompted me to take mestinon again after 2 weeks of suffering.
