When to announce

So I am almost 9 weeks and I got pregnant through <a href="https://glowing.com/glow-fertility-program">IVF</a>. I have seen the heartbeat via ultrasound LOTS as they have kept a close eye on me since the transfer. A lot of people were quite invested in the whole process and now are constantly asking how everything is going and if it worked! It's so hard to lie and deny since we are so excited! Everything has been textbook perfect on ultrasounds and the last one hade measuring a few days past and the heartbeat was 183! We are getting pictures done this weekend and I know I'm going to want to post right away! What are your thoughts?!
