Telling Boyfriend pregnancy news

So I'm/we're pregnant I'm super excited but I'm just worried that my boyfriend won't be we've discussed having a baby in depth and we were going to try this year anyway i just didn't think it would happen so soon and I'm worried about his reaction when I tell him. I'm sure it'll be fine just a bit nervous I guess it's such an amazing and huge thing to tell. What have your pregnancy reactions been like? And how did you tell him?
