30 pregnant and freaked out help lol

So I just found out I'm pregnant. My boyfriend and I broke up last year after a miscarriage and were separated for 1 yr and now we are back together it was a bad break up and my parents aren't very fond of him actually they don't really know we are talking again how do I break the news! I'm scared that he isn't come tell ready either. Even though he was the one wanting a baby this time.
