Pregnancy #2 after miscarried in June

I need some encouragement or ease if my mind. I had a miscarriage with my husband back in June at 11 weeks. We have been trying for almost 5 years not intentional but not avoiding it either if you know what I mean, we finally got pregnant and it was due on Christmas and then we lost it. This devastated us by all means, I still am upset everyday that I may have done something wrong. Now here I am pregnant at almost 6 weeks and I'm terrified of losing this one as well. I can't even be happy about it because I'm scared I will be let down. My husband is distant as well about This pregnancy because he wants to hear the heartbeat before he grows excited even a bit, how can I ease my mind at all with the fear of losing another one. I really want our baby to make it this time.....
