So I had a period in September, I put my nuvaring back in. However, I took it out 2 weeks later and had another period about 4 days later and that was October 1-7. I was without my nuvaring and it's now November 7th and I still don't have my period. I have had unprotected sex, using the pull out method, and tonight I took a pregnancy test with negative results. The past 4 days I've had light spotting with off and on light cramping. Should I see a doctor or is my body just messed up?
