Trying to Conceive

I've been tracking my cycle for more than two years, and it is basically the definition of by the book. We've miscarried twice, we have a 2 year old, and are trying for another and have been for 5 months, and still nothing. I know it could take up to a year, but I'm going crazy reading how tos, and seeing all my friends and even families birth and expecting announcements. Any other tips, experiences, encouragement, etc is welcome!
