MIL posted pregnancy announcements and I’m not ready

To preface: husband and I told his parents I didn’t want the pregnancy posted especially because my family doesn’t know yet. Well I told my family two weeks ago and was very serious about “I do not want it on social media until we are farther along and ready”. His parents asked “when can we post we want to share it with our friends” and I told them. You can text but I don’t want it posted.

Well I just went on Facebook and saw that my MIL not only posted the ultrasound but also tagged me in the post and said we are pregnant. I immediately called my husband and asked if he gave her permission (SO and I just had a conversation a couple days ago about when we would be ready) he told me no but said he would get her to take it down.

I am at work and on the verge of crying because I feel so frustrated. I personally see no reason that our families should be posting about it because to me it just feels like they are bragging to people. If they want to share it they can text whoever they want, I just don’t want it on social media. im not tryinh to be mean and bitchy but nothing in this pregnancy has gone the way i wanted with telling people and this is just another kick to the face. i dont even want to see my in laws anymore because they are going to ask when they can post and say they thought it was okay to posy about it. WHY NOT JUST ASK IF WE ARE READY. WHY WOULD YOU DO IT WITHOUT ASKING. i just want to leave work and cry. i am just so upset.
