A childhood belief about reproduction

I used to believe that when girls became women, they would start producing babies, much like a fruit tree produces fruit. I wondered how a woman's body knows when she is married, and worried that my body may be off, and start producing children before I got married. I went to my mother, and remarked, "I hope I don't have any babies before I get married." My mother responded, " I hope not too." I was the REALLY worried then as I knew it was possible!
