Trying to concieve

Hi Ladies. We've been trying to concieve for about 7 months and each month that goes by is just another disappointment. Trying to stay positive but is really tough. My fiance and I have been together for about 10 years and decided after we had my step son off to college and settled, that we ourselves would try for a little bundle of joy of our own. With that said it has been very difficult getting my fiance to understand the importance of timing. He is completely on bored but doesn't like the feeling of pressure. At times it is frustrating as he has had a child before and I feel I might value having one of my own a little more at this point. he has the attitude it will happen eventually, dont worry.....anyone in this same situation?? Any insight would be helpful.
