<s>[INST] i started taking birth control pills lutera 8 days ago, yesterday was the 28 day of my cycle, i had sex with my boyfriend but the codom broke, so i took a morning after pill (plan B) just after one hour that day; is there a risk i can get pregnant ?? thanks [/INST] Hi there thanks for posting your query at ChatDoctorDear as you have mentioned that you are already on the cops and that you took a pill one hour after the intercourse i as per my knowledge there hardly any chances that you will get pregnant. But every mechanism is not 100percent safe. They have there failure rate too. Which in this case may be less than 1 percent . So advice that you will have to whatever happens till the next period, till then stay happy </s>
