So many emotions

I'm just a ball of emotions this week. I cant even explain them all but mostly anxiety and worry with excitement and joy. We experienced a misscarriage back in august and of course are so overjoyed for this baby. We had a sonogram last week and babe measured a little behind what they should but had a good heartbeat and we plan on telling family at Christmas. I want to tell them for support but I'm also so nervous to tell them and not sure how I feel about all the questions that will accompany our announcement. Now I'm second guessing telling them but I also so want to announce at Christmas. I guess I'm just nervous because our last baby didnt make it.
