I had unprotected sex on the 15th (technally the 16th at around 1am) some cum got in me. my last period was the 8th an I am on a 26 day cycle around a week or more after sex I had some spotting light brown pinkish. On the 3rd this month right on time I got my period but it is really light and I also noticed that there was some strechy discharge along with my period. I've never experienced that so I am just not sure. Today is april 4th 2013.
