Do discuss both your plans and any worries that you have with doctors, and other professional staff looking after you. Pregnancy and childbirth is a time for continuing support. You can receive good advice, and possibly information about sympathetic obstetricians, from the local branch of the Multiple Sclerosis Society or other MS support groups.
In the past there was often very clear and very negative advice given about pregnancy to someone with MS. In general now this view has changed. A useful way to proceed is to discuss with your partner and/or family and close friends, a series of ‘What if ?’ questions, considering, for example, some of the problems that might occur financially or in relation to child care. Through these means you can rehearse some of the ways of managing potential difficulties, in the hope, and in many cases the expectation, that such problems will not occur.
Relapses tend to be lower in number during pregnancy, and overall most women find their pregnancy is relatively uneventful from an MS point of view.

Feeling good

Many women with MS feel really well while pregnant and would like that feeling to continue afterwards! What is almost certainly happening is that some immunosuppression is occurring naturally in your pregnancy, and lowering the levels of Multiple Sclerosis activity. So far it has not been possible to identify any of the specific hormones or proteins produced in pregnancy that produce this ef fect, although one pregnancy hormone has been identified, which suppresses an experimental form of MS in the guinea pig. So there is some basis for optimism in this line of research. However, applying animal-based research to humans has been a notoriously fickle and unpredictable process, so it would be unwise to expect immediate developments as far as people with MS are concerned. On the other hand there is an increased risk of relapse of your MS after delivery and if you should suffer a miscarriage (see below).

Taking drugs

As an important general rule you should not take any drug, even an over-the-counter drug, during pregnancy, or indeed when you are considering becoming pregnant, without discussing this first with your doctor. For many drugs used to treat the everyday symptoms of MS, there is substantial information available about the consequences of their use during pregnancy, and many of them are safe to use.
Those drugs that are now being used to treat the disease itself, rather than any one specific symptom, such as the interferon-based drugs (such as Avonex, Betaferon and Rebif) and Copaxone, are powerful immuno- suppressants, and it is still not clear what effects they will have on an unborn baby. You should stop taking such drugs once you have started trying for a baby, for it will be some time before you know you are pregnant and in the meantime the fertilized egg could be developing. It is a question of balancing your own concerns about the effects of Multiple Sclerosis on you, and the health of your unborn baby. The decision may not be an easy one to make, but most mothers treat the health of their unborn baby as their main concern at this time.
