It's not supposed to be this hard!

Ever since I started having intercourse Many years ago I've been so careful not to get pregnant. Little did I know it would take me years of trying and still no luck. It's not supposed to be this hard! Growing up it seemed people just got pregnant, easy right? Why did no one ever talk about the small window of opportunity or that miscarriages are more common than not? I grew up in this "fantasy" of when I wanted to get pregnant it would just happen. I know better now.
