I went of nuvaring last month around 15 had a cycle 1/16 normal 5 day but light had unprotected sex about 6 times since then. Period is 1 day late. Symptoms : sore nips (usually I get sore breast, this time only the nips) fatigue , a little white discharge, and have been getting this weird twinge like cramps for almost 2 weeks I think. That's the only thing that concerns me. It's not period cramps at ALL! There is no sign my cycle is coming.
