so annoyed with my job... people talking about me!

im a casual support worker in the community. Today i went and saw a client who said "i think you should know this but people are saying youre pregnant and i havent said anything but one of the girls who came here on wednesday said that it was mentioned in a work meeting that youre apparently pregnant. ..... i missed the work meeting monday due to illness but i do know that the boss has a strict "whats said in a meeting stays in the meeting" and ive had a co worker not only talk about me behind my back at this meeting but theyve also started telling clients. I am 10 weeks on Monday. I havent told anyone im pregnant and certainly not my boss until im atleast 12 weeks. I do have a little bump though so its possible people have guessed but STILL its nobodys business that im pregnant and n0w some stupid person who cant keep their mouth shut is busy telling the clients in the community that im preggo! so fficken pissed
