What would you do? Cancer diagnosis question

Ca

My sister is 40 and currently battling stage 4 Pancreatic cancer. Before her diagnosis she tried everything to have her second child and couldn't get pregnant. Now she has terminal cancer and makes comments to me about how much she wants to see me have a baby before her time comes. My mom does as well.

My husband and I are newly married, both have stable jobs and our own house. We make good money together but don't have much saved. We have chosen to wait until WE are ready to start trying.

But I'm curious, what would you do if your family put you in this situation or was pressuring you this way? Would you do it or follow the plan you and your partner are comfortable with and have agreed on? Do you think it is selfish of my sister to ask me to have a baby early just for her?
