Is it just me, or are there mais girls being born than boys the past few years?

Almost every pregnant person I know is having a girl. Out of 4 pregnant people I knew, one had a boy. Also, I watched this show "16 and Pregnant". It told the stories of 15 pregnant teenagers; out of both seasons six boys were born while ten girls (one had twins) were born.

It seems like having a boy is becoming a minority now. And this is kind of worrying me... =(
