No longer taking prenatals?

Brittany • November 2016 momma to a beautiful baby girl!
Is anybody else completely slacking, or just not taking their prenatals anymore? I'm 21 weeks and I have been slacking big time since probably 17. I completely stopped taking them probably at 19 weeks. I know they're good for the extra vitamins I'm missing in my meals, but is there any danger to baby at this stage if I'm not taking them? Anatomy scan came back perfect.
