Keeping pregnancy a secret

So I’m 21 weeks now and besides my husband and kids, only 2 other people know I’m pregnant.

I kind of enjoy keeping the baby our secret/surprise. My in laws are allllll drama and love to ruin and criticize anyone who has babies. My last two pregnancies were so stressful because of my MIL.

Am I bad for not wanting to tell?

I know eventually the beans will be spilled. I’m just taking my sweet sweet time. Husband said wait until 30 weeks. He’s down with keeping it quiet.

Also, we’re not going out of our way to hide it. Just not talking about it. In laws see us literally once a year (maybe).
