Be aware of flare-ups. In the first 9 months after birth, up to 40% of women with multiple sclerosis (MS) will have a relapse. However, a flare-up doesn’t raise your risk of a long-term disability.
If you had many flare-ups before pregnancy, you may be more likely to have one now. It may be a good idea to start taking your MS medicine right away to help stop one.
