Help! do you think it's a bad Idea to get pregnant at 43?

I have 3 daughter of my previous marriage , and been married for 12 years with my actual husband we've never had kids of our own, now my daughters have married too, and have their own lives and in all I have 5 grandchildren , I look young to the point that no one believes me I have grand kids, and it's not just to make me feel good, because mostly everbody tells me so. my daughters support me and don't have an issue about my age but at the fact that I already have grandkids, what would you recommend me.
