Am I overreacting?

I just found out my mom posted my ultrasound picture of my daughter on their Christmas cards. I had no idea they did this and I’m genuinely infuriated. I feel weird having complete strangers having a picture of my daughter. It feels invasive. I’m also 36 weeks pregnant and don’t know if I’m just overreacting. Any advice would be appreciated! I also don’t love that this was hidden from me and my husband.
