Prenatal vitamins are a good source of daily vitamins. But again, check with your doctor.
Im taking Womens One A Day (when I remember too, oops!) and extra vitamin C and a cranberry supplement to fight off a UTI (was that TMI, lol). I'm a 31/F. Vitamin D is important for women to help with absorption of calcium.

But again, check with your doctor and/or ob-gyn.
