baby wanted!!

Trying is fun, but its almost got to the point that we will only try when ever i know that i'm ovulating so it's like work. My husband and i got married July 2006 - i first got pregnant oct 2006, only to find out at 10 weeks i had miscarried, we have not been doing anything to protect, and we know that you should wait 3 - 6 months, we handled it as if it happens it happens, it's been been 6 months almost now and still nothing, i continue to track and keep record of my periods to better perdict ovualation, i'm just really frustrated, my husband is a 8 years older than i am and i just want him to enjoy his kids, and not be 60 when they graduated high school, so its a hurry up and wait process, i wish i could just pin point my ovulation to the T!
