<s>[INST] Hi. Had intercourse 3 days before my supposed period. I am regular. Condom broke but no ejaculation happened. I am aware that precum can get me pregnant. Question: do i still need to use nordette as ecp? Knowing that no ejaculation happened and I am not on my fertile window? What is the best thing to do? [/INST] Hi, Thanks for writing in. If your periods begin in 3 days time then everything is normal, and you do not have a pregnancy. If you do not get periods for more than a week after periods are due then you may have to think about getting a home pregnancy test after 15 days from the date of unprotected sex. This will give an accurate result if you have a pregnancy. Alternatively, if you do not get your periods then you can consult your gynecologist and take methyl progesterone twice daily for 5 days then within a day or two after stopping, you will get bleeding and periods will be regularized under normal circumstances. </s>
