Load up on fruit and fiber. Maybe even take a fiber supplement.
I've never really had this issue in my previous pregnancies, but a few weeks ago it got so bad that I was in real pain. I ended up taking Miralax because I couldn't stand it anymore and I was desperate. It worked within a couple days and I haven't had to take anything again. It was seriously bad! I hope you get some relief.
