should I or shouldn't I take prenatal vitamins?

So I'm very exited it's my first pregnancy!! 😬 despite what the app says (6w) I'm actually 4 weeks today confirmed by my dr in my first check out. The only thing that got me thinking was that she told me only should take 600mcg folic acid and nothing else if my nutrition was healthy, and that those prenatal vitamins only are good for the profit of the pharmacy. What do you think about this? I'm still worried that she didn't prescribe any vitamins. Of course they made my blood test to check that all values are fine. I wanted to buy the prenatal vitamins anyways but what do you all think? Does anyone had a similar experience? Thanks a lot!
