Advice? Please❤️

I have 3 kids and just found out I’m pregnant, around 4 weeks. This was unplanned and we were using protection.

My husband and I mentioned before we decided to not have any more about me not telling him until after the first trimester is over, he is a ball of nerves because our past history of miscarriages and he can’t handle another one, but because this baby was unplanned I’m not sure what to do.

I know I am not ready to tell him yet but I am not sure of when the right time is, or how to tell him.

So when do I tell him, and how do I tell him? Do I just say it? Or can I make it a cute announcement, is that insensitive to his feelings?
