Whats going on? Am I going crazy?
No, you are perfectly OK. It is a known fact that MS patients who become pregnant, often have a reprieve from the disease during this time. Some researchers think that a female's hormones play some part in masking and/or preventing the MS symptoms.
But the stats also show that after the pregnancy, the chances of an exacerbation increase. Hopefully, in your case, this won't happen and you can enjoy your period of remission.
