Monster in law keeps pressuring me to go public

Lynnise

So, During our planning of getting pregnant with our first child my husband and I agreed on not making my pregnancy public. We are exeptionally strong on this idea and since I'm now pregnant and we've told our closest friends and family we were happy to receive small baby gifts as we cant have a baby shower since were moving out of country soon. Beside this my MIL is continuously contacting me trying to pressure and guilt trip me to annouce my pregnancy on social media. I continuously have to tell her we won't. Even out of my husband and I's objections there are still the guilt trips. What can I do to get her to accept it, because it's getting to the point where shes slowly leaking things on her social media.
