I have been on Nuvaring for 2 1/2 years now and have just realized that alot of the symptoms I have been experiencing are related. I guess I was not educated before hand about this product...but now realize that my moodiness, weight gain (that occurred without any change in diet or exercise habit along with not being able to lose it after cutting calories and exercising more), headaches, and lethargy are caused by this product. I have already begun the steps towards getting an IUD insertion (sans hormones of course). However, I probably won't be able to get the IUD for another month considering I have to find a day that works within my work schedule. I am on my off week for the Nuvaring but am now thinking that I will not put another one in before getting my IUD. I cannot take the side effects anymore and want to start progressing toward a healthier life without nuvaring messing up the works. I guess I'm also disappointed in myself for not researching into the products I've used before putting them in my body. Now I know...especially with the help of these websites. Can anyone tell me what to expect when I stop the nuvaring? Should I expect irregular periods? relief of symptoms? etc?
