Congratulations!! With our first it wasn't planned or expected. I'd been feeling sick (unusual for me) and my periods were all over the place anyway. (Had no idea I'd missed one as had had some bleeding too.)
He said "look I'm going to get a pregnancy test, so we can rule it out." However, by that time I had googled "10 signs of pregnancy" and realised I had at least 4. I was secretly terrified - we lived in a shared house at the time, career was just taking off, not the plan at all.
I had a bath, trying to delay taking the test- he came upstairs and persuaded me to do it. So I did, but then refused to look at the result, so he knelt down on the floor to look at it, and looked up at me, his eyes looked really green and full of shock, when he said "It says you're pregnant" We were both in shock!
I should add this was ten years ago, we now have three children and often talk about how it was the best thing that ever happened to us! (Of course!) I didn't get a chance to think about how to tell him, as he told me. 😄
