I was given pre natal vitamin samples like PREQUE 10, CITRA NATAL ASSURE, CITRA NATAL 90 DHA, PRE NEXA,?

Pre Que 10, Citra Natal Assure, Citra Natal Harmony, Citra Natal 90 DHA, Citra Natal B-Calm, Pre Nexa, Dueat DHA Complete, and Prenate Elite. Too many to choose from, it's overwhelming already. So to the experts out there, what are the pros and cons for each of them should you have known and what would you recommend to me since this is my first pregnancy ever and I am working 5 times a week too. anyone?
