I'm on cryselle and have been for 6 to 7 months havent missed a pill and i am a sunday starter my pill intake is 9pm. I had unprotected sex on Sunday and took plan b with in 30 minutes . I had protected sex this Friday but the condom ripped and I'm worried I could become pregnant and I don't have the resources for plan b. I'm on my second week of pills with to remaining for this week. Could I become pregnant and do I need to take plan b?
