NuvaRing and absorbing

Hi,
I am a 36 years old italian girl,I apologize for grammar mistakes I will make, but I really want to share my bad experience with the ring.
I didn't find anything on italian websites, most of women simply find it great as I did for the first 5 minutes, but I soon started to experience strange effects wich I couldn't imagine were related to the ring.
The notice doesn't say many things!
When I inserted it, my period stopped to reappear after 15 days very heavy, this way I had a period of almost 2 weeks!
Second month I didn't have spotting, but I started experience chills and flashes as well as vertigos (and I was on holiday!) but I didn't think this could be the ring, as I say, the notice doesn't speak about this.
My cholesterol is higher together with 2 others levels in my blood analysys I am not able to translate.
Third month I gained 4 kilos in 2 weeks and believe me I am so concerned about my weight, always going to the gym and eating healhty. My breast and belly are huge as if I was pregnant and spotting is neverending.
I drink a lot of water, but don't go to the bathroom as much as I should, it seems I am absorbing all the water I drink!
Last thing my eyes are burning and it is getting difficult to stay to the computer
I will change b/c asap. I am happy I have found this site, it makes me feel that I am not alone.
Thank you girls
