First time mom. What can and can I not do?

Lillie

I know this is crazy but I don’t know these things. I have read and heard different stories. So I wanted to ask y’all. Can I get pedicures? Can I color my hair? What medicine can I take for headaches? What do y’all do for caffeine? I’m 5 weeks 4 days. This is my first time being pregnant and I don’t know what to do.
