I'm on Levora birth control and two weeks ago I was suppose to have my period. I had one spot of blood one day and then nothing after that. My boyfriend and I had sex when I was on day 2 of the "sugar pills". But later after I was suppose to have my period I started having brown gooey stretchy discharge and it's been going on for at least a week. I've also had light cramping along with it. What's going on??
