My mom died, and now I'm changing my mind

I lost my mom (62) to pancreatic cancer a month ago. I'm 32. For the last 3 years my husband and I have been leaning towards CF. However, as soon as my mom was diagnosed, the first thing I thought was I need to get pregnant. Of course as the dust settled I realized she wouldn't have time to meet this hypothetical child anyways. She passed away 5 months after diagnosis. But now, I'm pretty sure about my feelings of wanting a child. Is this normal? Why would it change my mind so aggressively. I don't want it to be because I'm trying to fill some void. Maybe it just put life into perspective?
