Pregnant again... when is it safe to tell others about another pregnancy?

Hi! I am 12 weeks pregnant today. I want to be excited, but also worried about getting my hopes up. I’ve had two miscarriages.

Last February I found out at 12 weeks and 5 days that my baby didn’t have a heartbeat and naturally miscarried at 13 weeks and 3 days. I also had a miscarriage between my daughter and son at 12 weeks and 5 days... 6 years ago.

Now I’m at 12 weeks today and don’t have another appointment until 16 weeks. I’m nervous about the pregnancy, but am hopeful that the baby will be okay. I haven’t told many people and I’m not sure when My husband and I should tell our kids at least...

Prayers would definitely be appreciated for my families peace of mind!
