Im hardly 2 months pregnant and my mother in law is asking me to check for unborn baby's gender

I got married 1.5 years back and I'm now pregnant with my 1st kid and its just hardly 2 months of pregnancy. Just last week me and my husband went for the check up and were very happy to see our baby in the ultrasound image. Later when we came back home, and my husband rushed to his mom saying the little one has grown compared to the last week, her first question was, "So, now can we know the baby's gender?". My husband said no, its a tiny little one! So she further added, but doctor must be knowing it for sure. And the conversation ended as I personally was in shock to hear this weird question coming from her for the innocent one who's still growing. She sounds weird to me , not just this time, but many-a times. Now I have come to my parent's place for staying and I have informed my parents regarding her bullshit thoughts. My parents tried speaking to her to know her real intentions and she said go and first try to improve your daughter's mind. She's completely negative and bla bla.. She insulted my parents completely and my husband is in complete control under her hands and will not speak a word for me or against her. Also his mother can't see my husband taking care of me. Please guide me. What should i do? And how should handle this situation.
