He isn't ready

Lili

I had a talk with my hubby and he says he isn't ready to be a dad yet.. unfortunately I'm scared my time is running out. I had an ovarian cyst removed when i was 12 and i lost 40% of my ovaries along with the cyst.. I'm currently 23 going to 24.. am i being irrational or do i still have time to have a baby later in life
