Need words of encouragement

After one miscarriage and one blighted ovum. We are finally pregnant with our rainbow baby. I had an ultrasound at 7 weeks and 6 days and we saw a tiny baby with the most beautiful heart beat. We couldn't hear the heart beat and the doctor said that is perfectly normal because it's really tiny. We announced to my husband's parents and now everyone knows. Didnt want to take the excitement away from my husband but its hard for me to be positive or get extremely happy because I'm soooo scared something can go wrong. I have another scan in 2 days and im crying my eyes out because I'm scared of something going wrong and now everyone knows. Any positive words would be greatly appreciated 😊
