My life or my baby?

Hey everyone. I just found out I'm pregnant. Now I have 2 kids already. 4 yr old. And a 11 month old baby boy. When I went into labor with my son, it didn't turn out so well. I ended having a emergency c section and then my vitals and heart rate when off the charts. But I pulled through. I was sick and don't remember the labor or the whole day my son was born. I didn't become conscious of my whereabouts til later that evening. The dr said I scared him and he thought they would have to take me to ICU because I was saying "I'm so cold" but i actually wasn't. They had to put a warm blanket on me that was like aired up and stuff. So now I'm pregnant again. 6 weeks. The dr told me that it's possible that I can get sick and I can get worse with this baby so he is saying this will be a high risk pregnancy and labor because of how it turned out with my last one. I went home. Prayed. Spoke to my husband. He said "I believe in God and I speak life". I believe in him too but there slight fear because of my 2 kids. That's my deepest fear. To grow up with no mother. I told my husband about it and he is all positive and refuses to think otherwise. I'm not gonna lie. I'm scared. When it all comes to it for the labor, I told my husband to save our baby. He walked out from me while saying "no. It's not gonna be like that. Y'all will both make it. And if the dr says I gotta choose. I'm choosing you because I can not live without you". I don't know what to think. I have feelings everywhere.
