Negative change symptoms and conditions

I am currently on my 3rd NuvaRing. I had been on approximately 8 different pills since 2004 and could not find a solution for my CONSTANT bleeding. I have Endometriosis and I was only having about 5 days of the month that I was not bleeding. This has actually been going on for about 14 years but getting a lot worse since I came off of the Norplant in 2004. Since being on the NuvaRing, this is the first time I have gone more than one month with a completely normal period. I have noticed a decrease in my sex drive but not a complete death, I am paying attention. I am having slight heart palpitations for the first time since coming off of the Norplant, so I know those are from the NR, but not too badly or frequently. Headaches on the last 3 days before it comes out but otherwise. And absolutely NO pain or bloating associated with my period (I used to look 4 months pregnant most of the time). So far I am happy but am watching carefully. I have noticed a negative change in my attitude also but am not convinced yet that it's the NR since I have been through a lot recently. I will keep you posted.

UPDATE:
I went to my gyn on Monday and told the nurse how I was feeling and that I wanted to switch BCPs. She spoke to the dr. and he refused to switch me. He said if I didn't like it to just stop it but that he wasn't going to give me a prescription for another BCP. That it was too soon to see any side affects and to give it another two cycles. She later said it might be the sudden surge of horomones that might make me feel that way. I told her I don't know but i felt really mad and not myself although it was two weeks everybody else noticed a huge negative change in me as well. Mind you I am a brand new patient and this was the first prescription this dr gave me. I had not take BCP for alomst 10 years so I don't know what his problem was. Now the only thing I can think of is I am very overweight... ... but aside from that I don't have any other health problems. so is this the only pill that can be prescribed to obese women?????? I am so disappointed in my dr, I was excited that he was only 2 blocks from me but I am switching.
