A case of the spots

himmel
Okay lovelies,
So i literally had my period last week and and it ended early due to a Plan B i took because my boyfriend and I were unsure of whether or not he got sperm inside of me (we had sex with a condom but we were still unsure because it broke near me). Then today I had cramps, woke up tired and got a period that lasted for probably three hours. what is this all about..?
