gilmoregirl's Trying To Conceive Wish

my husband and i have been ttc for nearly 18 months now with no results and we've tried almost everything short of actually doing invasive tests with the doctors and its killing us because i have a 4 year old girl by my exhusband so we know i can get pregnant and have the ability to carry a baby to term with no problems. we would really really like to have a baby of our own plus we're getting pressure from his family since he's the oldest boy for him to carry on the family line.
