trying to concieve

Hi ladies, I am brand new to this so bare with me. I am 23 years old and my partner is 31. we have been trying to convince since January so that's almost 10 months. to be honest I've started to give up. we both have a lot of work related stress and I am assuming this is a potential threat to me conceiving but it can't be helped. we used to worry why we hadn't conceived yet but when our friends were telling us to relax more and not think about it we stopped. We don't have sex all the time as we are both so tired when we finish work, we arrive home around midnight on most occasions and we work 6 days a week. I really need some advise. Please help me.
