13 weeks for me
I told my mom and best friend immediately, because I just couldn't contain such excitement after over a year of trying and I needed the emotional support! But I made everyone else wait until the 13 week mark, when I felt safer. (Although, everyone at work was already speculating on my belly shape and consistant pass on Starbucks! One skinny, single woman actually had the nerve to say behind my back, "She BETTER be pregnant, or sistah needs to get to the gym!!" The NERVE!!)
