When did you announce to your parents?

When did you announce your pregnancy to your parents? I am very close to my parents but they didn’t know i was trying for a baby so I am trying to decide on the right time to tell them. My husband and I have known we are expecting for 6 days, and we are 6 weeks 1 day. It feels super weird not telling them immediately especially being that I’m 6 weeks, not 3-4 and I’m already feeling VERy pregnant (nauseous, tired, sore boobs, dizzy) so I feel like it will be hard to keep a secret from them. I live on my own but I am around them a lot. I love my parents and want to fill them in on the excitement but I don’t want to rush it. When did you tell your parents, especially if you are close to them? I probably won’t be able to get my first ultrasound until closer to 10-13 weeks.
