Suddenly nervous..

N

So I am about 7 weeks but because of my miscarriage history I’ve been a little off and nervous, so I had a scan at 5w5d saw a tiny little bean the smallest. I have another scan this week about 7w6d-8w and I’m all of a sudden so nervous. My sons 10 months old and I didn’t tell any family members my so and I wanted kids very close. I’m scared of being judged. How do I announce??💕
