Frustrated!

I had a miscarriage two years ago and now I am six weeks pregnant!! I'm really excited but I don't want to tell people till I get past the 12 weeks. I told the two girls I work with because the morning sickness is so bad. I got a little nauseous at work today and the girl I was working with went and got the manager and we told him I needed to go home then stood there and said "you have to tell him" and literally forced me to tell him. I haven't even gotten a chance to tell mine or my partners family. I know I'm going to be moody right now. But I literally want to rip her head off!!!
