which is worse – unplanned pregnancy or menopause?

i miss my period last month, and i’m still looking forward for it this month.  i’m alwasy regular., and the  last two times that i missed  my period both resulted to babies.  so right now, you know what i feel. totally scared, anxious! mannn, i don’t want another unplanned pregnancy, plus  my 2 kids are just a year apart, and the youngest just turned one.  not a good scenario to get pregnant again . gawd,  i’d feel the most irresponsible person in the world if ever i’m pregnant.
