Coffee and Other Confusion

I think I ovulated yesterday, even though it was only day 12, and now I'm doing everything I told myself not to do!  I'm feeling "different" today, even though I know symptoms don't show up this soon.  I also went online to see when my due date would be if I am pregnant.  I was happy to see that it would be mid November.  I don't want my kid to have a birthday too close to Christmas.  Why can't I just convince myself to not think about being pregnant?

Because I could possibly be pregnant, I spent a half an hour this morning trying to decide whether or not to have coffee.  I switched to decaf when I started trying to get pregnant because I figured it would be best to go without caffeine.  I have never been someone that drinks it every day, but I usually have one cup 3-4 days a week.  The other day, though, my brother-in-law mentioned something about chemicals being used to decaffeinate coffee.  I decided to do some research and found a lot of conflicting information.  Some people think its totally safe to have 1 cup of regular coffee a day, while others say to stay away from it completely.  In regards to decaf, some say the amount of chemicals left in the coffee after decaffeinating it is so small that it isn't an issue, while others say you are better off drinking regular coffee than decaf because of the chemicals.  There is decaf coffee that was decaffeinated using water instead of chemicals, but I don't have any and I've heard it is expensive so I finally resorted to going totally without coffee.  I just feel like I can't take that risk because if I am pregnant, now (and the next few weeks) is the most crucial time in the baby's development. 

I just wish there were more clear yes or no answers in regards to nutrition during pregnancy.  I don't want to do anything to harm my baby, but I don't want to go way overboard either.  Sometimes I think about how many people just live their lives like they always did and have totally normal, healthy babies, but I know that's not the attitude to have.  I guess I'll just continue doing my best and trying not to stress about it.  It will be easier when I know I am pregnant.  March 17 can't come soon enough!  Yes, I set a date to take a pregnancy test so I won't keep taking them too early and wasting them!
