Pregnant again..

I am 13 weeks and couple days pregnant, my son just turned 7 months. Last pregnancy I told my family that I’m pregnant and he told his family that I’m pregnant even though I wanted to do a little pregnancy reveal for them like I did with my family. But my husband went behind my back and told them already 🤷‍♀️ I was a little upset but I got over it, however this pregnancy I am not telling anyone, I told him as soon as I found out we are not telling anyone I want this one to be a secret. I haven’t been getting along with his family ever since we started living with him, so I don’t want to share my joy with them, they disrespect me, look at me up and down, talk about me behind my back. They are just bunch of hypocrites. I haven’t told my family I only told my sister but she promised not to tell anyone. I don’t want them to know because my mom doesn’t want me to have another kid right away she wants me to at least wait 1 or 2 years, so I’m kinda embarrassed or shy to tell her that I got pregnant when my son was 5 months 😔. I just don’t want them all looking down at me like “Wow, she couldn’t even wait a year or 2 to have another baby” or “wow, she is soo thirsty” I am an African, and let me tell you AFRICANS are sooo judgmental ! I just want to know if I’m wrong for keeping this pregnancy a secret? I’m happy that I’m pregnant again, My husband is hoping for a girl this time. I just don’t want to be judged when they eventually find out 😒 I know I shouldn’t be worrying about people’s opinions but when it comes to family members it’s kinda hard to ignore their opinions 😔. Any thoughts on what I should do???
