Constipation

Rachel
This might be TMI but I'm 9 wks pregnant with my second child and I've been badly constipated. I've been eating fiber and drinking lots of water and just started a stool softener and only went a tiny tiny bit in the past couple days. If it persists, I'm going to call my OB but does anyone have any other advice? Anything besides what I've been doing? I also have been eating yogurt and drank some prune juice. And trying to walk around more to get things moving. Thanks!
