Hello, Welcome to HCM and thanks for asking your query and i would do my best to solve your query. First of all, i want to tell you that nordette is a kind of oral contraceptive pills containing ethinyl estradiol and levonorgestrol. It should not be used as an emergency contraceptive pills. Also it should be avoided if you are already pregnancy, because it mainly prevents ovulation, so if already a pregnancy is there, it can lead to birth defects. You had unprotected sex 1 week before the expected day of your period, then there are very rare chances that you become pregnant. So my advise to you is stop taking these pills again and wait for your normal period to come and if it doesnot come in time, do the pregnancy test and if it comes positive and you don t want to continue, then consult a gynecologist to abort it rather than taking such pills. You can take misoprostol 800 microgram intravaginal or under your tongue to abort it. Hope this will solve your query and feel free to ask any more questions even directly to me.
