When my son was 18 months old, we decided to try for a sibling. My first pregnancy ended in an early miscarriage. I quickly became pregnant again, and once we passed through the first trimester, I breathed a sigh of relief.
I was 22 and 2 months away from graduating college. My boyfriend at the time had made it known early in our relationship that he did not want me to have an abortion if we ever got pregnant, but the moment we were confronted with this, he decided that he didn't want to be a dad.
My first pregnancy was an accident (do NOT trust "Fertility Awareness" methods!!), but at the time I was pro-life so I kept it, even though I ended up with deep depression and a life-threatening illness.
