What Causes Vaginal Spotting After Taking Next Choice?

                              question, took next choice as directed within 24 hours of condom mishap... came off but... we think it came off after sex as there were fluids everywhere outside of the body... next choice was simply a precaution... was not ovulating... about a weak later spotted for about 2 days... then nothing since, period due in about a day or two... a little nervous... is the spotting normal? could I be pregnant? additionally after sex took a shower and cleaned with soap to change the ph level in a hope to kill any sperms left...
