Pregnancy

Hey everyone, I need some advice. So I was 6 days late on my period today, and I decided to take a pregnancy test. The first one came out positive and so did the second one. When I told my partner he was happy! We have been together for 3 years now and he is extremely happy to have a baby. I’m happy but at the same time I’m freaking out. It was a completely unplanned pregnancy and now I can’t go to sleep cause I’m so scared that this is going to change the little things that me and my partner love to do. I don’t want to lose the little things we love to do. I just need some advice on how to make this feel more positive then negative.
