Hi N.!
I know exactly how you feel! 7 years ago, I was in your place, and about your same age. A friend in Denver recommended a book called, "Taking Charge of Your Fertility" by a Seattle author Toni Weschler. Wow, what you'll learn about your body will astound you! I was pregnant the third month of trying, and in the best shape of my life! (I was training as well, what a great way to go into your pregnancy, makes it a snap!)
I really suggest you get a copy of the book! (I know of 6 women who've successfully used the book, I can't believe no one recommended it!)
Best of luck to you!
