TMI... Constipation

Anyone else dealing with constipation? This is my third pregnancy and the first time I have had do deal with this. I have irritable bowel syndrome and constipation is something I use to wish for. Wow I had no idea lol! Ive talked with my ob and tried their suggestions from more water to juices and even had to go as far as stool softener and an enema. Any advise would be greatly appreciated. I'm at 12+6 I can't imagine keeping this up for 6 more months. Thanks in advance!
