I had unprotected sex with withdrawal 4 times in a night. I was on CD9 at night and cd10 in the morning. My cycle is usually 25 days. I took plan b 2hrs after the last round. On night of CD 11 I had side cramping like I usually do during ovulation. Today is cd 14, I have not had any side effect at all. I had white thick discharge last night and that was all. Can I be pregnant? What are my chances?
