How do i tell my boyfriend that im pregnant?

This wasnt something we planned, or something we are prepared for. Everytime i try to tell him i get scared and chicken out. I dont know how he will react to it.

Im 22, hes 23. We've been dating for over a year and we currently live together.

I dont know how to start the conversation, or what to say or how to say it. Ive tried multiple times now and the words just dont come out.

So far all he knows is that i havent been feeling 100% lately, he hasnt questioned it at all.

How do i tell him? What do i say? How do i say it? I don't want to completely freak him out but i know that he needs to know.

Any ideas or suggestions?
