To announce I'm Facebook or not....

Ok so I'm in a dilemma ladies. I seriously want to announce I'm Facebook finally that I'm pregnant and I'm having a boy. (I don't want to reveal his name until he is born) I just don't know how to go about it, or the judgement. I don't remember my sister in-laws posting this early (going on 13 weeks) but then again I knew before Facebook that they were pregnant. Then my mom said to me "she wouldn't post until has born" I said well people are going to post about the baby shower. Idk I haven't been super active since I found out I was pregnant last November... is it okay to post or should I just really now.... 😣😣😣
