Baby blues

So the past few years have been hard on my body. Ive been diagnosed with an inoperable brain tumor. Doctors advised me back in 2020 pregnancy is an added stress to my body and my body cannot take it. Back then, my youngest was only a few months old and i wasnt thinking about further pregnancies. However now i am so broody and we are feeling ready to expand our family. I am so upset yet feel so selfish. I want to be the best mummy i can be and i know that further pregnancy could potentially put that at jepordy. I cant help feeling this guilt and desire. I know that there is other avenues and there are women who cannot conceive naturally at all and im thankful i have my baby already but i need a little feeling sorry for myself moment! Anyway has anyone else experienced anything similar to this? How do or did you deal with it?
