Thanks for your query.
Around the time of ovulation, chances of pregnancy
with unprotected intercourse
are pretty high.
However, you are reasonably sure that the condom was perfectly intact.
Also, you took plan B
well in time.
I would say with a double back up, chances of conception are quite low.
But there is no 100 % guarantee.
I hope you realize there is no point of freaking out right now.
YOu would know if you are pregnant only when and if you miss a period.
Stay cool and calm until then.
take a pregnancy test if you are overdue.
