Wanted to post my experience to help possibly ease someone's mind. I had sex the day after my period ended on February 25th and the condom broke (did not realize until after everything was said and done). Took Plan B within 10 hours or so. Experienced bleeding from March 3 to 8. Had sex again on the evening of the 8th and didn't use a condom the whole time (this was so stupid an what caused my anxiety for a month - don't be like me!!!) Started my next period on April 7th... so about 2 weeks later than my typical cycle and 4 days later than my "Plan B cycle". This was of course after tons of worrying, reading things online, home pregnancy tests, and even a blood pregnancy test that all came back negative. Try not to worry, but if you are truly concerned, go buy a home pregnancy test or even research places that can do blood pregnancy tests in your area. I was able to find a lab that could see me the same day and the test was only $50. Blood tests are more accurate than home tests and it really made me feel better once I saw it was negative. Seeing your doctor is alway a good idea as well. Good luck!
I'm here to tell my and my girlfriend history.
We had sex on July 18th with condom, but it broke, so we got plan 48 hours after. Unfortunately, she reacted like VERY BAD to it. After 6 days, she had a 4 days bleeding ressembling her period but a little less.
Fast forward to August 28th, her period still hasn't come, we freak out and go for a preg test... NEGATIVE. later, on september 5th, same history, still no period and do 2 pregnancy test, neg again.
BUT two weeks after that, her nipples got sensitive and she starts having cramps. We both feel like dying so we go for a blood preg test... NEGATIVE! but her period still doesnt show
Fortunately, today September 28th her period has come. Keep in mind that is like 64 days after her plan B bleeding and almost 84 days of her real last period. Worse summer ever, relax a little, most likely your period will come.
