Hi, I d my periods on the 5th March, and on 9th I d unprotected sex with my partner. I took Levonelle (Plan B) within a 12 hour period. On the 15th of March, I d a three period/ withdrawal bleeding(slightly lighter than usual). Now it s the 12th of April and I still haven t had my normal period. I did get a few PMS symptoms in the last week like lower abdomen pain, slightly sore breasts (this one only for the last 3 days) and now I don t even have that. I am worried as hell. Please help?
