*I'm not on BC*
My boyfriend and I had PROTECTED sex on March 30th. Well out of precaution, I took the Plan B pill and I got my period 4 days earlier than scheduled. My period started on April 13th and lasted until the 17th.

Well, on April 27th we had PROTECTED sex again and I didn't take the pill again. We checked for holes and tears numerous times and nothing. He never ejaculated in or near me. I am now three days late for my scheduled period.

I've felt very bloated for the past 2 weeks, and for the past couple of days I've felt mild period-like cramps. I've also been really stressed lately over exams and this stuff.

Could I be pregnant?
Is there a chance?
Could Plan B be affecting this period?
Why do I feel like this?
