Announcing pregnancy?

hope

Just found out yesterday there is definitely a bun in the oven!! I've taken like 7 tests, they are so faint but 6 of them all showed positive!! I'm so excited I wanna go just shout to everyone but also it's so so early! I'm only 3w3d. I told my family of course already, and told 2 friends and the sperm donor. But the people I'm really excited to share this with are my work friends. Should I tell them after I go to dr wed and hopefully get bloodwork done or should I wait? I know it's up to me but I'm just too excited to think clearly haha.
