Hello samantha, how far along are you? First of all you should purchase the book what to expect when your expecting. It will answer alot of your questions. Also available is what to eat when your expecting. It is also a very good book. But if you can/t get them just eat healthy, try to get lots of protien and fruits and vegies lots of fluids and a good prenatal vitamin.
Keep in touch. Im 14 weeks pregnant with my third child, so you can ask me any thing.
