How to tell husband about unexpected pregnancy?

DH and I were going to start trying on our 5th anniversary. Our 3rd anniversary is here and somehow I am pregnant. We had another accidentally pregnancy that ended in an MC last year and he was so freaked out, he wouldn’t talk about the baby for like 3 days after finding out. I felt alone and sad that he wasn’t excited. I know he was shocked and unprepared but so was I, I just quickly realized it was time to rally and prepare for baby even though it was waaaay before I was ready.

How do I tell him this time? I want him to be happy. I am nervous but happy and I just don’t want to feel alone in this just because it is happening sooner than we planned. We are using pull-out plus I’m on lutera.

Any ideas?

(Ps, he loves kids. We talk about names and activities and trips we want to do with our kids and he’s comfortable talking about it and he even has pointed out baby clothes he likes so I know he truly is excited for when we have kids, I’m just worried he won’t react well since it’s sooner than planned)
