I totally understand the frustration... haven't gone in four days myself and starting to stress about it. Funny thing is, my own surgery is supposed to have the exact OPPOSITE issue, but I'm the weirdo that even confused my surgeons office, go figure! Anyway, I hope you can figure out something that'll work for you. I've upped my fluid even more than normal, have taken Milk of Magnesia, Miralax, and bought stool softener I have yet to try and... Magnesium Citrate as my last resort because that stuff is NASTY! 🤮 My surgeons office had me cut out banana's and told me to cut out my iron for three days and just take multivitamins without and then once it clears up go back to taking only TWO instead of the THREE I WAS taking. I've decided since it didn't work LAST time (I was constipated last week too) I'm cutting it down to one with Iron and two without. I'll just tell my primary and she can do my labs more frequently to keep an eye on it since I see her on Tuesday anyway. It's frustrating, painful, and incredibly annoying! I hope it clears up for you!
