anyone take ritalin while pregnant? | ADHD Information

I am 13 weeks along, and have taken my meds at a lower dose.  I can't find anything negative regarding ritalin during pregnancy, but I am still concerned.  Has anyone here taken their meds while pregnant, and if you did.... was the baby affected in any way?  My ob said she hadn't heard anything bad and it should be okay, but still.  I want to hear any info, good or bad, so I can make a good decision for my baby.  Thanks!wow, nothing!  I'm 21 weeks now so it's been a while since I asked!  Hope to hear from someone about this.
