I'm 18 years old and was diagnosed with IBS - D about 11 months ago, and struggle with it constantly. I've noticed that ever since my IBS symptoms began, my periods have become a lot worse (longer, heavier, more cramping, etc). Also, my IBS gets worse around my period, especially the week before. I mentioned this to my doctor, and she said the hormones from my bad periods could be causing my IBS to flare up more. I'm going on the pill to help my periods at the end of May, and I saw some people on this website saying the pill has negatively affected their IBS. Has anyone else dealt with this? I will be sooo upset if the pill worsens my IBS it is already a pain! Also, has anyone else noticed their periods getting worse possibly due to IBS?
