Do I want a baby or a slice of Pizza

I got my period today and my heart sank... I can't possibly take care of a baby, I'm a student, in a new relationship, I wouldn't afford it and I am 12 000 km from home but somehow... my heart doesn't understand that... It just wants a baby to love, to nurture, to change nappies and teach... for cuddles and hugs and long sleepless nights... Orrrrrrrrr maybe it's PMS... let me have a food instead
