My boyfriend and I had sex 2 weeks ago, I took a pill within 36 hours, although I was on my ovulation date, (I'm on a 28 day cycle), but I'm irregular, so I don't know if I was ovulating or not. We were having sex with a condom and it did not break, but we are stressing it might have leaked out the bottom :/

Anyway, it's been 2 weeks since the accident and my breast have been pretty sore lately? I've had this before, although I'm unsure what is going on. My period day is suppose to be today, but nothing?

Am I pregnant?
Is this a side affect?
Help thankyou

- the pill was a 2 dose at the same time, it's the first time I've used a ECP
