Screening and telling

This waiting is just killing me! I want to tell everyone that I'm pregnant! Unfortunately, I'm also a worrier and so is my husband. We have decided to wait until after we get first trimester screening done to tell people, but that seems to far off! I'm at 8+3. Plus I'm not sure how long things are going to take because I'm in the process of trying to change my provider. The one I had is too far away and I see someone different every time I go so it kinda sucks. I'm especially disappointed because I wanted to tell a few of my coworkers on the last day of school because I won't be seeing them for a while, but now I don't feel like I can. 😞 When did you tell? Did you get the screening? And should I really be worried? (I'm 27 and hubby is 30)
