Hi health seeker,
Welcome to HealingWell!
Yes, the pill can definitely exacerbate IBS symptoms. When I was on a high dose pill (1/35) my IBS what at its worse. I got off it for several months, got better, then went on a lower hormone dose (1/20). I'm much better now. My doctor told me that if even the lower hormone dose was flaring up my IBS, he would have liked me to try NuvaRing. It is inserted vaginally into your uterus, which emits the hormones directly to the source. It won't need to travel through your digestive system like the pill does.
You should talk to your doctor about
BTW - I take probiotics daily. They help tremendously.
