Stressed by in laws about gender of baby

My in laws are very traditional (extended family too) about giving birth to a boy. My firstborn is a girl, and although they love her a lot, I know that they still yearn for a boy, and I find there’s nth wrong with that. Now that I’m pregnant, when I went for my 8th and 12th week checkup, my in laws keep asking, when will know the gender? Can the dr check the gender yet? They even went to the extent of questioning my firstborn (want didi or meimei), and forcing her to say didi till she was so frustrated, tries to ignore when they ask, giving both answers didi/mei mei at different occasions and keeps crying when they insist she has to say didi. The relatives are the kind that go “it’s ok you can try again for a boy” when I was pregnant with my girl. So the whole vibes are always boys better than girls, must give birth to a boy. I am so stressed as I am nearing to my 16th week checkup, which may have a slight chance to know the gender soon. For me, gender doesn’t matter but it’s really annoying to keep hearing these comments. Sometimes I really pray to give birth to a boy so that I can finally shut all their mouths because it’s just so irritating, and so that I can have my third or more children with a peace of mind. I keep telling my in laws that a healthy baby is most important, they will say yes yes, but still saying and giving non constructive comments. So stressed with everything already. What should I do...
