Congrats! A couple of suggestions for you:
1. Check out the thread for moms due in the same month as you -- get to know those ladies who you will be going through this journey with you.
2. Purchase a book (or two!) and maybe a journal about pregnancy -- I like the week-by-week ones myself. My husband likes to read it each week to see whats coming up with the baby and with my changing body in the coming week. I have a daily pregnancy journey that has a spot every 4 or 5 days to write my feelings and moods in (for posterity -- ha!). I think it will be neat to look back at both when I get pregnant again and for my kid(s) to look at years from now.
The books can answer many of the questions for you about what to be careful of, what to eat and what not to eat, what activities are safe, etc. Also, your doctor will probably give you a BUNCH of paperwork, books, pamphlets, etc. at your first visit (usually scheduled when you are around 7 or 8 weeks).
3. Check with your medical insurance co. (if you have one) about any special programs they have for pregnant women. Mine (BCBS of AL) has one called Baby Yourself where they have a nurse assigned to me that I can call with questions anytime during normal business hours and who calls to check on me every month. She also sent me a bunch of literature about questions I had (like about the various tests --CVS, Quad Screen, Amnio--) as well as some other goodies, like a 32 oz. insulated mug that I fill with water 2-3 times a day to make sure I'm getting enough fluids each day. They are motivated to make sure that pre-natal care is topnotch to decrease costs in case a problem arises that could've been avoided. It's nice to have that person I know I can call...
4. Use the search function on this board when ever you have a question -- chances are it's been asked and answered before (you are not alone!)
Sometimes that's enough... If you do post a question it may take a day or so for people to get back to you.
And whatever you do, use common sense! Your immune system is greatly in flux right now (it's trying to figure out what this foreign thing is inside of you at the same time that other parts of the body are saying --- wait! This is a wonderful circle of life happening here.) so you are at risk for many things that are normally cautionary for "children and the elderly."
Again, congratulations, and welcome to the Pregnancy board!
