I've only been taking the Azurette for about three weeks now and since the 2nd or 3rd day I've been experiencing cramps, from mild to severe. I've also been very emotional and have gained some weight. I'm more bothered by the cramps. Does anyone know if the cramps will go away in a couple of months? Or should I switch to my old bc, lutera, although it's been about three or four years since I took them last.
