Telling people..

So I am very excited to be pregnant. I am totally sucky at keeping secrets. It’s very hard for me! I am only 3 weeks and 5days. When should I tell people? Like I want to wait until I am at least a little far into it. I just wish I didn’t know I was pregnant right now. My boyfriends parents are coming up next weekend to visit and I really want to tell them then. But hell, I’ve heard if you tell people your pregnant while early on your more likely to have a loss. Who believes in that? When did you tell people?
