I started using the NR four monhts ago. In the begining things were great but then it started coming out durring sex, not just every once in a while but all of the time. I started to gain wight, have constipation problems, and very bad headaches. I was still planning on continuing using the NR but then it was decided that we wanted to try to have a baby so I stoped using the NR about a month ago. Since I have stopped using the NR I have still not had a period. I have taken 2 test and both tests have come back negitive. I called the customer service number for the ring and they are saying that this is not a side effect of the NR. The headaches ave gotten somewhat better.
