Absolutely. You have changed, you have grown a bit older, and new recommendations come out all the time, especially if your last pregnancy was a while ago.
Think of this as a review session, where you and your OB/Gyn will go over your prior history, but add any pertinent new changes. Maybe you have had new medical problems, medications, surgeries, or new pertinent family history.
It's also an opportunity to review your prior successful pregnancy and delivery. If there were any complications or issues with the prior pregnancy, this is the perfect time to discuss prevention and treatment options for the next pregnancy.
Screening for Down syndrome and other chromosomal abnormalities will have to be rediscussed based on your new (older) age.
Prevention is always better than cure, and rediscussing all issues at a dedicated preconceptual counseling session can only be beneficial, no matter what number pregnancy this is.
