Someone please read this! - I'm desperate for feed back. I will try to keep this short.

I was really skeptical about starting Nuva-Ring. It was honestly a last resort, I've been deemed "hormonally unbalanced" and was suffering from serious depression as well as various other medical complications. I've been light headed, dizzy, and suffering from extreme headaches for the last 4 years of my life. Prior to Nuva-Ring this included having crazy mood swings, painful and inconsistend periods, and all the awful shit us girls get to endure.
I've been on the ring for the past 5 months or so. At first I loved it, I mean I wasn't thrilled about having to insert it and what not but it was so nice to only have to do something twice a month- major points for convienece! I was still experiencing crazy mood swings and i'm told it "comes with being a women" but I refuse to settle for feeling miserable all the time. Atleast on the ring I could see the major break downs coming - I notice I am super emoitionally "sensative" on days I take the ring out and put it back in (which makes sense becasue my body has to readjust).
Any how I became sexually active for the past 3 months almost worry free.
I had a pregnancy scare a while ago, took a test it turned out negative but since then i've been getting increasingly dizzy and exhausetd (this is really nothing new so it didn't alarm me at first.) But I'm getting absurd sinus headaches around 6 pm if not sooner EVERY day and feel INCREDIBLY nauseated when I think about eating anything and it's very hard to keep anything down I have to really focus on controling my gag-reflexes. I also noticed my breast are super tender, I've been getting all sorts of discharge, and honestly my vigina hurts a little. I'm pretty new to the whole sex seen so some of that is expected but this just strikes me as a really odd combination of things. I did a ton or research on my own.
I really want to leave the doctors out of this because in every experience so far I get diagnosed, treated and then I come back with more complications (talk about job security).
Any how the game plan right now is to run out, take another pregnancy test (hopefully rule that out), and if that's not the answer (*fingers crossed) then I'm seriously considering discontinuing Nuva-Ring. But this scares me because 1- my body will most likely be even more weird having to adjust to being ring-less again (Nuva ring was a good choice for me because I had low estrogen so back to more imbalance- if I was ever stable in the first place). 2- I actually have sex now and the birth control aspect is nice because i'm not actually ready to have a kid - and I still use condomns but have bad luck and do NOT want to end up with a baby right now(grant it I would accept responsibility and cope but I would prefer to avoid it). 3. This could not even be Nuva-Rings fault but a huge inconvenience and I can't tell if i'm better with or with out it because I've been so messed up either way.

So any advice/i.e. suggestions would be GREATLy appreciated, i'm noticing alot of similar issues among previous comments but also a few differences. Thank you for you time!
