I hve been on the nuvaring for 7 months now. My in/out day used to be Tuesday. Last month I took it out a week early by mistake. I had to wait until the next Thurday to put it back in because the pharmacy would not fill the RX early. I put it back in on Thursday the next wk, waited 7 days again for the rig to become effective, but did not have unprotected sex until about 10 days after inserting the ring. Normally when I take the ring out, my perios starts within 3 days. It has been 5 days and no period. Could I be pregnant?
