MIL Issues /hubby

Drama dram moments that irritates the hell out of me My hubby and I lost our son in still birth last year. It's bloody frustrating as hell when my mil keeps asking us to try to have another kid and to do it quickly. In my previous pregnancy I used to wear a pregnancy waist band to help elevate the pressure to my waist. She recently told me not to wear it for the next pregnancy. Like seriously, does tht affect? My husband just does nothing to shut her out. Now I'm currently expecting again and decide not to tell my parent in laws the good news. How do I dread announcing /my belly showing to reveal. What should I do and handle this?
