Nuvaring for heavy menstruation ?

Hey guys,

I'm a 22 year old female. Over the past 2 years my periods have gotten really severe. I now get heavy bleeding (like I have to change my tampon every hour for the first day or two), extreme nausea, terrible cramps, dizziness almost to the point of fainting, and sometimes even migraines.

I finally went to the gyno 2 months ago to see what he could come up with. He said that he thought my period was definitely too heavy for someone my size especially (I'm only about 95 pounds) So he started me on the nuvaring. I'm now two periods into this bc and my period was still so bad today that I had to actually leave work. I felt awful doing that, but I thought I was going to pass out. I've been tested for anemia before and it's always come back negative. I should also mention that I have an anxiety disorder which generally gets a lot worse right before and during my period. I think the anxiety makes my period symptoms a little worse and vise versa, so it can be hard for me to tell, especially with something like dizziness, what my body is actually going through and what's just "in my head" so to speak.

My question is this, has anyone had these symptoms, tried nuvaring and had it help at all? If so how long did it take till you noticed your symptoms improving a little? I think I need to just give this another 2 months or so, but I hate having to leave work because of something this stupid. It makes me feel so unprofessional. Thanks for reading, sorry this is so long!
