Wallstreet symptoms and conditions

I was put on the NuvaRing by my OBGYN to fix endometriosis... that was 5 1/2 years ago... I'm now 26 and I have been having dizzy spells for a while... actually passed out twice while living in New York for the past 4 years... not fun when you're on the Subway! Recently - the back of my legs started hurting! Then my calves swelled up! All these new veins appeared and I rushed to my general physician! The first thing out of her mouth was are you on birth control... GET OFF! When i told her it was NuvaRing - she was 99% sure it was it! I had an ultrasound to make sure it wasn't blood clots and it's not... so I went to nuvaring website and one of their symptoms is pain in back of knees and swelling! RIDICULOUS!!!! I took it out immediately! Even the 32 year old who did my ultrasounds said she voluntarily got off all BC because of everyone she has come in there with liver, blood, heart problems!
