Ugh!!!!!

Autumn • You screw me, I screw you back. I`m a lady like that.
I'm so friggen constipated! I'm 30+5 weeks and oh my gosh! I've been drinking water, cranberry juice and apple juice like crazy and it's barely chugging along! Three going on four days of not pooping!!! 
Do any of you ladies have something that works good? Looking for something natural.. Cranberry and apple juice usually works for me :(
