"my doctor prescribed me necon 1/35 after my horrible experience with trinessa. i took necon for about a year and had absolutely no problems with it. i did experience nausea the first 2 days of each new pack but as long as i had something to eat, it wasn&#039;t a problem. periods were light and only 3 days. i had no problems with weight gain or any side effects really. i really would have stayed on necon as long as possible except my pharmacy has now switched me to another generic called nortrel 1/35 which is suppose to be the same so lets see.. one thing that really isn&#039;t the biggest deal but i appreciated was the packaging on necon. now that i am on something else with way cheaper packaging i miss my old pills. all in all, i would recommend."
