Plan B or its equivalent is available in most drug stores and through the internet without a perspiration. It is ideally used within three days of an accident, more effective if sooner. Any one relying on condoms for contraception should consider keeping this on hand. It is about 90% effective. I am a little unclear as to the elapsed time since the event. If you ovulated which occurs mid way between two periods, and found the condom in two days, then your period should be about 12 days away. But if another week has passed before writing, then Plan B is unlikely to help, and it is also outside the longer window for an IUD to prevent pregnancy. The amount of content in the condom is not a factor. It is possible to be pregnant from an untreated mid cycle condom accident. I hope that you have the outcome you want. Thank you for consulting us and I hope I understood and answered your question.
