Raging hormones or am I right?

So first of all, I've always had a strained relationship with my dad; to the point where we wouldn't talk for years at a time. We've been ok for the past couple of years, so when I found out I was pregnant at 5 wks my fiancé and I decided we would tell our parents and siblings but hold off til 12 weeks to let everyone else know. We told our parents and siblings to not tell anyone until we were ready. So last week my dad and I got into an argument. Today was my nephews 1st bday party and all of my family was there. As soon as I seen my uncle, he asked me if I was having morning sickness. I was livid. He said my dad had told him. I told my step mom that I told them I don't want anyone to know. She said my dad was just happy. I told her it wasn't his news to tell and she agreed. By the end of the party, everyone was coming up to me telling me congratulations and asking when are you do? They told me my dad had told them. He even told my moms side which she was so hurt because she was waiting to tell her own sisters the news. Which they were upset bc she didn't tell them. I don't care if he is happy or not. It was not his news to tell and I feel he did it to hurt me knowing that I was planning to make a big and special announcement to my family. Is it the hormones or am I valid in being completely pissed?
