We promised each other we wouldn't go crazy....

When my husband and I were in pre-marriage counseling the topic of kids cam up. I knew I wanted kids but my husband helped raise his two younger brothers and niece and nephew so he isn't jumping up and down to have kids. Although, he has always told me if I want them he wants them. We promised each other that when it came time for us to start trying we wouldn't go crazy with it.... you know come off the pill and do what we do. We had this joke that with our luck we it would take a lot of work, or he wasn't fertile(our sisters just had to breath the same air as their S.O.'s so we didn't think anything of it). As of now we are 8 months in to trying and have had a chemical pregnancy/early miscarriage and I know compared to others this isn't a long time but to me it feels like an eternity. And those jokes are definitely NOT FUNNY anymore. I am silently freaking out and crying while he is at work. I have talked to him about going to the Dr (he says he is going to make an appointment) and I have had him taking vitamins so have I. I just don't know whay to say I want to talk to my sister but don't want to go behind my husband's back and it just seems like everywhere I go/everything I do there are babies or pregnant ladies everywhere. Does anybody have advice on keeping call or coping with ttc?
