How can I open up about TTC/infertility?

My husband and I have been TTC for almost 3 years and had a miscarriage. No one knows about any of this though.

I want to be able to open up with our families and be open about it on social media. I have a TTC Instagram account, but I want to be open on my personal accounts as well.

I just don't know how to bring this up. It's not exactly something you just blurt out at Thanksgiving, you know? We don't see our family too often, at family events and occasionally here and there to hang out, but that's it. I'm not extremely close with my family and we have never been the type of family to talk about our issues or feelings. I think that's why I'm struggling to figure out how to bring this up.

Please help! Like really walk me through this, step by step like you are talking to a dummie. That's how foreign this whole concept of opening up is 😕
