iPill/ Unwanted 72 is not a suitable option, due to common side effects such as vomiting and delayed periods(which can be confusing and scary) and also known to cause irregular bleeding. It is prescribed in a single episode of accidental unprotected intercourse and therefore, is not designed for repeated acts of intercourse after consuming the iPill. If you have unprotected intercourse in the first 9 days of your cycle and thereafter from the day 22 your cycle (Day 1 is the day you start having menstrual bleeding), chances of pregnancy are very low, so you can try that. If your husband has sufficient self control, & if willing he may try withdrawal method, just prior to orgasm & ejaculation, though the failure chances are high (25% failure) with this method. A condom is also effective only 97% of the time. You may try a female condom, made of polyurethane.
