Tertle,
It is good to hear from you. Indeed your wife needs to tell the doctor. It coud be just a pregnancy thing or a host of other problems. The thing is you are probably making it worse by not going to the doctor. The stress of not knowing has to be making things worse. I know that I had a bunch of little things pop up when I was pregnant. My childhood asthma came back to stay (thanks boys! :). My doctor used to say, "pregnancy is pathology". I think both of you would feel so much better knowing either way. I have heard of one other couple that just happened to both end up with MS. Although this is not a good thing. They were doing just fine managing their diseases together.
You are in my prayers. I hope to hear from you soon.
