What products should I buy?

Ana
Hello, I just found out I'm pregnant. According to the app, I'm in my 6 week. I'm not taking any thing right now (I mean pills or anything), so what products do you think I should buy? Please help me! I don't live in the US, but I'm here because I was in a cruise ship with my family, so I have to buy the products here (even so it's way less expensive here)! What should I buy?
