AITA for refusing to end my pregnancy despite my mother-in-law pressuring me?

I have been married for 10 years. The first two years of my marriage were very difficult because I couldn’t get pregnant. After that, I had three children, and they mean everything to me.I take care of my home, my children, and my husband. I always try to take care of everyone, even when I’m exhausted myself.Recently, I found out that I’m pregnant again. At first, I kept it from my husband and mother-in-law because I was scared of how they would react. But as the pregnancy has progressed, I’ve started feeling unwell.When my mother-in-law found out, she told me that I should end the pregnancy. She says I already have three children and that I won’t be able to properly take care of another baby.I told her, “How can I end my own baby with my own hands just because you want me to?” She became very angry and started saying hurtful things to me My husband knows what is happening, but he has remained quiet. That hurts me the most because I need his support right now, but he hasn’t stood up for me in front of his mother.I know another baby will make our lives more difficult, especially because I haven’t been feeling well. But I don’t think I can end my pregnancy simply because my mother-in-law thinks three children are enough.AITA for refusing to end my pregnancy despite my mother-in-law pressuring me?
