Pretty much everyone. Most of our friends knew we were trying and when i stopped going out for drinks they put two and two together and figured it out. I had to tell my boss because I will be leaving my job after the third or fourth month and he needs to find a replacement (I'm so nice giving that jerk a 2-3 month notice). I told one of the ladies in the office (she knew we were TTC) and she screamed which brought the other ladies flocking to her office so they all know. This was the second day I knew I was pg. So we then decided to call our respective parents who then told the rest of the family and family friends...umm...vicious cycle? I really wanted to wait until the magic three months but DH pointed out that if I miscarried, everyone would find out anyways, so we might as well tell them.
