What Are The Side Effect Of Nuvaring?

Hi, I am 19, 5 3 an weigh about 110 lbs. I just started the Nuvaring at the end of my last cycle. I was on the birth control pills for about 2 yrs and had regular periods after. I have always had regular periods but I ve been hearing and reading some really scary things about how Nuvaring can cause infertility soon after you stop using it. I want to try to get pregnant within the next yr or so, but this is making me very nervous now.
