Hi I have some questions about me possibly being pregnant. I had unprotected sex well ovulating, I knew I was ovulating because I have a calendar, I took the plan B pill one step 11 or 12 hours after but I m experiencing cramps , sore erect nipples, and craving a lot of food. I m 16 and just need to know if maybe my egg was fertilized before I took the pill,please let me know.
