Plan b, cramping a week later, normal? i had unprotected sex a few times over 2 weekends ago, we were just worried about "pre cum" . i took plan on the monday after. that was 1 week ago today. i am due for my period in approx 8 days. i am having bad cramp

The : The symptoms you are describing are likely pre-menstrual. When Plan B is taken it can disrupt your normal cycle, so expect that your period may come a little sooner. However if your period does not come by the date it's due you can take an early prediction pregnancy test (morning urine is always best). Good luck.

Maybe side effect or: premenstrual sx. Potential SE’s w emergency contraception: tender breasts; changes in menstrual flow (spotting, bleeding, early or late period or spotting instead of period); loose stools; dizziness; headache; nausea/ vomiting; abdominal discomfort or feeling tired. If you develop chest tightness, difficulty breathing, swelling of lips, mouth, throat – call 911.
