Should I?

I keep going back and forth on if I want a baby. I had a miscarriage when I was 18 now I'm 22 and I've been with my boyfriend for almost a year living together. He's almost 30. We get along pretty well and I love him but he says he doesn't want kids and I want to be 25-27 ideally when I have a baby because I have at least 5 more years of college. I guess im not quite sure where I'm going with this but I'm scard I won't be able to have a baby and also shiuld I wait that long I'm worried about cancer my whole family has had it and had breasts and uterious removed.
