Hello, I took Mircette for a year and stopped taking it due to some problems that occured by me taking them.. (Read my other post on "Withdrawal affects of Birth Control Pills) to get an in depth story of my experience of taking them and stopping them.. The health problems that arose with me weren't immediate/common ones like most (weight gain, nausea, irregular periods), but were gradual problems that occured over time.. Some of which were (low blood sugar problems, and an array of symptoms that stemmed from something called Intestinal Candidisasis, which is an overgrowth of natural yeast in your intestinal track, that can be triggered in excess by some hormone pills), which for me was Mircette.. Birth Control pill brands affect people differently, but in my case with Mircette it totally messed my health and reproductive system up. I'm gettin' better since beng off of them, but it's been quite a challenging road in getting back to my normal self.. Hope your experience is better, should you decide to get on them.. Take Care..
