Terrified but anxious to announce!?

Hi guys! I thought I would post here because this is really getting to me.

I have an almost 6 month old, and Im 6 weeks and some odd days pregnant! While my husband, I, and our close family are all excited to welcome our next little one, I am terrified of the backlash and judgment we are going to get for having babies 13 months apart. I wanted to announce after our ultrasound this coming week, but I'm terrified and filled with anxiety. I guess I'm looking for support and positivity because people can be so cold. :(
