Keeping the secret

Imma • Newlyweds and pregnant with our first! God has blessed us and I am so excited to embark on this journey.
It is so hard not to tell everyone I see about our first pregnancy. My mom lives several states away and I want a cute way to tell her. My boss is also a close friend and can't wait to tell her. I feel I should soon because we work with TB, MRSA, Cdiff, and a lot of X-rays and I'd prefer to be separated from those surgeries. 
So, you ladies are my audience. We're pregnant!! I bought a journal to record my feelings and little notes to baby that I will give them when they turn 18. The only thing I am feeling (besides elated) is an increase in heart rate (and no caffeine for this lady). 
When did you tell your boss, family, friends, and then social media?
