@MrsMom - while folic acid is one of the most important supplements in early pregnancy (b/c it reduces the risk of neural tube defects like a cleft pallet) other things like Omega fatty acids (for eye and brain development) is also very important, thats why its important to ask then which one they recommend you to take - if she doesnt have a preference, the "preferred" ones are PregOmega + and Centrum Materna DHA. I know @STK takes PregOmega, I took Centrum Materna before and I am still deciding which I will take now. While I was trying to conceive, I just took the Vital Pregnant Plus supplement as a good all round pre-pregnancy vit.
Yes EDD is for estimated due date, and VBAC is vaginal birth after c-section. Toxoplasmosis is something you can get if you have cats (i think they are the main source, but you can get it from other places too) that can be potentially fatal to your unborn child, so they test for it to see if you either have it or have anti-bodies for it (as far as I remember). Dont know if all doc's test for that, but mine did.
I also thought of something else you can ask - its just good to know you doc feels about that. There is this guy called Prof Nicolau who is the end all and be all when it comes to prenatal scans. He is the guy that most doc's send you to (in JnB) for your 12-13 week check up (where they check for the syndromes - that is if you want to know of course). He is very expensive (most medial aids only pay a portion of his fee) and is almost always booked solid - this is why I say ask your doc if they want you to go see him now so that you can make an apt asap to see if you can get an apt straight off the bat of if you need to get on the wait list.
Seeing him is of course completely up to you and your husband, and not saying that your doc WILL ask you to go see him, but if they do, its best to get onto his wait list soon b/c he is almost always solidly booked. You have do decide if you want to know of any potential issues, if you are happy to just see your doc then thats perfect too.
Anyway, thats a lot of information, sorry, I tend to ramble on some times
