Had sex condom on, she used ecp after 3 days (nordette) overdosed took another set coz she forgot instructions. pregnant? pregnancy chances? 98

Sex with condom: If you had sex with a condom then the chances of pregnancy are very very low assuming it was used correctly. I do not know what you mean by overdosing on emergency contraception or forgetting the dose so I can not comment on that. If condoms were used the ECP was not needed. If you think you might be pregnant check then check a home pregnancy test. They are cheap, reliable and available at any pharmacy.
