Moisturizer

I'm a first time mom. I have no idea about cosmetics or beauty products that are suitable for pregnant. I searched but I cannot gumble buying it without asking experienced moms. I cannot ask my mother and my mother in law as they didn't use anything when they were pregnant. Any advice as to what's best moisturizer for a pregnant woman. Like particular product. I am in may 15 weeks of pregnancy. Thank you for your ideas.
