When we got married, neither John nor I wanted to start a family right away. We both figured that we would wait until our relationship had time to really cement before we introduced children. We had no idea that we were frittering away our fertility on birth control. When I was 36, we decided to start trying to have a baby. After 7 months of trying unsuccessfully to get pregnant, we visited a San Francisco fertility clinic. The doctor told me that women over 35 often have difficulty getting pregnant. If I had known before I would not have wasted time on the pill.
