Im 9 weeks pregnant. But am i wrong for this?

Hey gals, i just needed to vent and see if some one has ever felt like this or maybe im just overreacting.

So when i found out i was pregnant i was maybe around 5 weeks so we told our parents. But told them to keep it a secret bc we want to wait til we went to the doctor and make sure everythings ok and i wanted to wait til i was 3 months to tell ppl. Well we went to doctor and got our picture. My bf sent it to his dad and he immediately told all his family and created an event on fb for my bf and i for sunday. I didnt say anything but it kind of bothered me. Im not ready to tell all the family yet.

Tomorrow is the event and i was just talking to my bf about it and my bf gets upset saying that its his family its no big deal. I just told him that when you reach the 3rd month the risk of miscarriage isnt high anymore. And i dont want to have to go through that "im so sorry". i wish his dad wouldnt have done that. Im not ready to say anything yet like i said. And my bf says that theyre just family theyre not people but yea he has a huge family and also his dad told his employees some of his employees know my mom and they told her. And she told me. Thats how i found out that he started telling everyone. I get it, hes excited. But im the one thats pregnant not him. And my bf doesnt even understand me. Ugh im so annoyed.
