We aren't agreeing on when to tell. Pregnant with my rainbow.

I had a miscarrage back in May, and I am now almost 6 weeks with my rainbow. The first time around, we told our families as soon as we saw them in person after finding out around week 5. This time we agreed that we wouldn't tell anyone until the second trimester. I am very adamant about waiting until week 14.

We have a wedding on his side to go to around 11.5 weeks and out of the blue, he tells me he is just going to tell his family then. We just had a huge fight about it. It was so hard to have to explain the situation the first time. His justification is that he will do all the explaining and not me. I'm so f***ing hurt right now. I don't want anyone to know, and I feel like he is basically saying f**k my feelings. I told him, "You want to tell them, fine, you tell them on your own, I don't so I am not going." What are your feeling and advice on this?
