Looking for some support

I’m starting my second year of teaching in a the middle of August. My husband and I have decided to start TTC. We are so ready to start our family and I intend to be a stay at home mom for a few years while our kids are little. I have found myself fearing lately of what others (my colleagues) will think about my decision to start a family so soon into my career. All I’ve ever wanted is to be a mom. I don’t know why I’m so worried about their opinions. In reality, they’ll probably be kind and supportive...but my worries are still keeping me up at night. I guess I’m just looking for some support.
