You will probably have your first appointment between 7 and 9 weeks to confirm your pregnancy. They will do a urine test and some doctors do an ultrasound to confirm. Drink plenty of fluids, water is extremely important. I saw some moms say they don't worry about caffiene and that's okay for them, but I do watch how many caffinated drinks I have during the day. I have a hard enough time sleeping and the caffeine just makes it worse for me, so I may be more tired throughout the day, but I sleep pretty well at night. I was drinking 2-3 cups of caffinated tea a day, but have switched since I read this article linking it to miscarriages: http://www.babycenter.com/0_caffeine-during-pregnancy_3955.bc. Definitely limit gatorades and powerades - drinks made to replenish your eletrolytes are not good to be consumed by pregnant women heavily. They contain a lot of sodium and it's not good for you or the baby. One every once in a while will be okay, just not a lot. Stay away from Ramen noodles - I don't like them anyway, but it goes back to that sodium intake thing. Tuna if you like it is fine to eat and so are many other kinds of fish, you should get a list from your doctor of the recommended kinds. Fiber is super important to intake. Your baby is going to absorb so much of what you eat that you can easily become constipated. I have with all 3 of my pregnancies! So I have to make sure that I eat enough during the day or take a supplement like citracel. I also have to take a calcium supplement because my babies tend to absorb so much of my calcium that it starts depleting from my teeth and you can see the stripes in my teeth where it's coming out. I knew this from my previous two boys so I just went ahead with this one and started taking it from the start, but you may not need too. Post whenever you have questions! Good luck!
