Need some girl support..

I only have one girl friend and I don't get much support from her... I'm TTC month 5.. My husband has three kids and I have one. I'm dying for another. We don't have any together. I've told him how badly I want a baby and he says he does too and told me not to take my bc anymore but he doesn't want to "try-try". So I'm all on my own pretty much. I use ovulation tests and I can feel when I ovulate but it's so hard getting DH to BD!! It's so frustrating and he doesn't seem to care very much! Idk what to do. With my first, I was off Bc for 8 months and my first month of ovulation testing we got pregnant. I'm on third month of ovulation testing and still nothing.. Getting discouraged....
