Irregular Periods Explained: The Main Reasons Why Your Period Is Out of Whack

Birth Control Pills

A woman’s body can take several months to adjust to the high level of hormones that birth control pills provide. Additionally, one of the side effects of a low estrogen birth control pill is a light or non-existent period. For many women, this is a positive side effect. However, when women decide to stop taking their birth control pills, their cycle may take a few months to operate normally again. Birth control pills do not always cause women to miss their period; sometimes it might be once a woman has stopped taking birth control that they find they have hidden hormonal problems that weren’t visible due to being on the pill.
