Birth Control and Periods

Stephanie

I have a question about Nuva rings. I had it in for a month and my period came a week before I was supposed to take it out and my period seems lighter than usual. My doctor said I was supposed to take it out when I was expecting my period and then it would start. My question is: Is my body just adjusting to the hormones and every person is different or is there something wrong with my birth control?
