I'm kinda nervous

my boyfriend made the decision to cum and we had thought the condom was fine until he pulled out. it broke. he couldn't get a plan b for me until the next day which was over 12 hours later. I took it after work and that was maybe 20 hours after his accident. he finished in me on my most fertile day too.

well. last time I took it, it made me have a period.

it's been a week and nothing has happened. my actual period isnt suppose to come for another week.

is this normal or should I be worried?
