For all you guys with constipation sorry if it's tmi

I am now six weeks and four days. I'm on extremely high doses of iron which can't be avoided. Dr. prescribed me stool  softeners and I've been on those for two days. Has been four days since I had a bowel movement. I'm starting to feel really uncomfortable and I think it's actually making me more nauseous. Is there anything you ladies would suggest maybe trying to help myself go?
