Pinches symptoms and conditions

I have to say I'm really, really bad with taking pills, so nuvaring is pretty much my only option as far as birth control goes. (plus I'm getting married soon, so I'm hoping that it's not the ring)
I've had Nuvaring in for 9 days now (my first time using it) and I've begun noticing some odd things. I can't say I'm super-attuned to my body, so I'm not sure if it's the ring or not.
My gynecologist says I have Poly-Cystic-Ovarian-Syndrome, which means I probably have cysts on my ovaries. I'm also overweight. Recently I've noticed cramping and pain on my right ovary. I've also noticed slight depression, but I'm also going through finals, so not sure there either. I'm experiencing little pinches of pain in different spots all over my body, especially in my arms, legs, and back. I also had an unexplained nosebleed out of the blue this week, and I've never had one before. (no nose trauma or anything) I'm also noticing I'm bruising very easily, but I'm not sure at all if that is recent. Are these side effects of the nuvaring, or something more serious and unrelated? (or else just stress maybe?)
