I told as soon as I had a positive pregnancy test. I only told my siblings, mother, best friend, and of course my bf.
We have told a handful of people I am 10 weeks on Saturday and the Monday after I am 12 weeks is my scan so we are telling people straight after that if everything works out well
We waited til we were over 12 weeks to tell everyone but had our families told before than
I bet that's hard! Lol. I told people right away! May I ask why your doctor is recommending that? Usually people start telling their families around the beginning of the second trimester since the rate of miscarriage goes down tremendously! It is all your own discretion though(: goodluck and congrats!
