I have had ibs like symptoms since starting levonorgestrel + ethinylestradiol birth control. could this cause gas, bloating and loose stools?

IBS: oral bc cause?: Oral bcp's are just a version of what your body goes through hormonally during a regular (non-pill) cycle. IBS can be caused by stress of any kind, or by viral/bacterial gastroenteritis. Bcp's are not involved in causing IBS, but taking them irregularly can activate endometriosis by causing estrogen levels to vary in strength. Implants in the colon are common and can lead to IBS symptoms.
