TTC can't seem to get it right!

I have been TTC for 2 years and in bout ready to give up and not have any kids. We have tried what my doctor recommended, having sex every day of the month, ovulation tests, and bbt. Bout ready to give up hope. We are both 27 and want a baby. We have been paying attention to our projects and work so that we are not Solely focused on getting pregnant. What else can we do to help?
