On November 25th my boyfriend and I had sex but the condom broke. I took Plan B about 4 hours later at most. 6 days later (On Dec. 1st) I started bleeding. I thought it was my period but it only lasted 3 days and was a lighter flow than normal. My period does not usually start until the 13th of every month. Today is now the 15th and still no sign of my period. I did notice a small amount of white discharge last night though. Please let me know what you think? Thank you!
