Maternity Clothes...Help?

Rachel

So I went to Macy’s looking for Maternity wear. I don’t really have a noticeable bump yet but my pants are tight enough that it’s uncomfortable. Finding pants was easy enough but are maternity tops basically just extra long loose fabric shirts? Everything felt so thin and long and looked the same? Sizing wise do I size up? Do I choose my same pre pregnancy size? Where should I go for more options for work/not TShirts?
