Any idea

Samantha
I'm currently having extremely painful cramps, like on a scale from one to ten, there a twelve! Usually my cramps are a four to six but that's only when I'm ovulating or af is paying a visit. But I already had a visit from af. I did have sex recently and it was unprotected for maybe a few seconds but that was right before my period started. Any ideas on why I'm cramping so badly?
