I have been on levora for a month and a half so far, after changing from tri sprintec which I was previously on for 7 months. The discharge is only after I have intercourse and it's not a lot, but I'm just wondering if this is normal? The discharge is around the beginning-middle of my cycle. Can this be a sign of pregnancy? Also, if I felt nauseous from the pill and threw up 5 hours after, is my protection compromised? I also missed a pill on my last pack but made it up by taking two the next day. My levora pamphlet says I do not need a backup method of only one pill was missed, could this be pregnancy?
