1 month pregnant? Good for you! I have a suspicion I *might* be as well; we'll see. I wrote a journal about my last pregnancy in 2009-2010. It went from week 17 until my delivery. I was never perfect with my diet but did a pretty good job and learned a lot about my body. It was far easier than my first pregnancy, during which I ate like crap. I think eating health(ier) was relatively easy during my pregnancy because I felt like more was at stake. My first tri wasn't good, but after that it was pretty smooth sailing. Take care of yourself for the next two or three months and hopefully it will get easier after that!
When are you due? Is this your first?
