Can hormones affect bowel movements?

Usually I would only go once every to every other day. I recently found out I have a hypothyroid and PCOS. My Dr put me on a medication to correct my thyroid and birth control to lower my testosterone. About a month or so after I started these meds, I starting going about twice a day. Nothing in my diet has changed.

Since my hormones are regulating, could that cause my bm to regulate as well? Or is there no correlation?
